How Many Hotels Should You Invite to an RFP? The 5–8 Rule

Quick answer: for most corporate events, invite 5 to 8 hotels to your RFP. Fewer than 4 and one weak reply kills your negotiation leverage; more than 10 and you spend more time comparing proposals than you save on rate — and hotels can tell they are one of twenty, which quietly moves your RFP to the bottom of the sales manager’s pile. The right number for your event depends on three variables most planners never write down — here they are.

Why the number matters more than planners think

Inviting hotels to an RFP feels free. It is not. Every hotel you add costs you twice:

• Your time on the way back. Every proposal that lands has a different rate structure, different F&B minimum, different attrition clause. Normalising ten proposals into one comparable table is an afternoon of work. Normalising twenty is a lost week.
• Hotel-side prioritisation. Hotel sales teams triage inbound RFPs the way you triage cold email. An RFP that reads like a targeted, qualified request from a planner who has clearly shortlisted gets a sharp proposal. A blast that has obviously gone to every hotel in the city gets a template response at rack-adjacent rates — or silence. You cannot see the CC list, but experienced sales managers can smell it in the brief.

So the goal is not “maximum coverage”. The goal is the smallest pool that still guarantees competitive tension after the inevitable dropouts.

The reply-rate math

Work backwards from what you actually need on decision day: at least 3 comparable, qualified proposals. Three is the minimum for real leverage — with two you have a coin flip, and the hotels know it.

Not every invited hotel replies. Some are sold out on your dates. Some skip small events. Some sales inboxes are simply slow. If roughly half to two-thirds of a well-targeted list responds with a usable proposal — a realistic planning assumption for corporate MICE inquiries, not a guarantee — the arithmetic looks like this:

You invite	Usable proposals to expect (plan for ~50–65% response)	Verdict
3 hotels	1–2	❌ One dropout leaves you negotiating with yourself
5 hotels	2–3	✅ Minimum safe pool for a standard event
8 hotels	4–5	✅ Comfortable — supports a proper BAFO round
12 hotels	6–8	⚠️ Only worth it for large or multi-hotel programmes
20+ hotels	10+	❌ Comparison overhead eats the savings; brief reads as spam

That is where the 5–8 rule comes from. It is not a magic number — it is the range where the expected number of usable proposals lands between 3 and 5, which is exactly what a clean comparison and a credible BAFO round need.

Adjust for your event profile

Invite fewer (3–5) when…

• Your dates are flexible and your block is small (under ~15 rooms). Small, flexible business is easy for hotels to say yes to, so response rates run higher and you need less redundancy. For very small meetings, an RFP may be overkill entirely — see when an RFP is worth it for small events.
• You have history with the hotels. Repeat business gets prioritised. Two incumbent hotels plus two challengers is a perfectly good pool.
• The destination is thin. In a secondary city there may only be four properties that genuinely fit your spec. Inviting a fifth that cannot host you just adds noise.

Invite more (8–12) when…

• Your dates are locked against a citywide event. Congress weeks and trade fairs compress availability; expect more “sold out” replies and pad the pool accordingly.
• The block is large (80+ rooms) or spans a shoulder weekend. Fewer hotels can physically take it, and several will decline after checking the group ceiling.
• You are new to the destination and cannot pre-qualify from experience. Widen the funnel, then cut hard after the first screen.

Quality of the shortlist beats size of the blast

The single highest-leverage step happens before you send anything: pre-qualifying which hotels get the invitation at all. A shortlist built on actual fit — capacity for your headcount, meeting space that matches your format, location logic, a track record of answering RFPs — outperforms a bigger unqualified list on every metric that matters: response rate, proposal quality, and negotiation speed.

Pre-qualify on four filters, in order:

• Hard capacity: can the hotel sleep your block AND seat your plenary on the same dates? If either fails, it is out — no exceptions.
• Format fit: a boardroom-heavy leadership offsite and a 300-pax product launch shortlist look completely different, even in the same city.
• Location logic: transfer time from the airport or from your office, walkability for evening programme.
• Responsiveness: if you know a property never answers RFPs inside a week, its slot is better spent on one that does.

What your RFP looks like from the hotel’s side

It helps to picture the desk your RFP lands on. A group sales manager at a city-centre corporate hotel is juggling dozens of open leads at any moment, and each one gets triaged in minutes: dates checked against the group ceiling, value estimated from block × rate × nights plus F&B, effort weighed against the odds of winning. Three things move your RFP up that pile, and all three are visible in the first thirty seconds:

• Completeness. A brief with firm dates, headcount, room split, meeting format and budget band can be priced same-day. A vague one goes to the “chase for details” folder, which is where momentum dies. Our RFP checklist covers the fields that matter.
• Winnability. “One of six shortlisted, decision in two weeks” reads as a real opportunity. An anonymous blast reads as somebody else’s deal.
• Fit. If your spec obviously matches the property — headcount inside their sweet spot, dates in a need period — the proposal that comes back is a bid, not a brochure.

Pool size is part of that signal. Six well-chosen hotels each believe they can win and act accordingly. Twenty hotels each assume they won’t and staff the reply accordingly. The paradox of the wide blast is that it produces more proposals and less competition.

A worked example: 60-pax offsite, Lisbon, October

To make the funnel concrete, here is how the numbers play out for a typical two-night leadership offsite:

• Long-list: 14 properties from a first sweep (search, past events, colleague recommendations).
• After the four filters: 8 survive — two fail plenary capacity for 60 cabaret, one is mid-refurbishment, two are too far from the airport for a Thursday arrival, one never answered last year’s RFP.
• Invited: those 8, identical brief, 10-day deadline.
• Replies: 5 usable proposals, 1 polite decline (sold out — a citywide congress overlaps night one), 2 silent.
• Shortlist: top 3 by weighted score go to the final round; the winner comes from renegotiated terms, not from the lowest first offer.

Five usable proposals from eight invitations is the healthy middle of the funnel. Had we invited only the “obvious” four, the congress-week decline and the two silences would have left two proposals — and a two-horse race hands pricing power straight back to the hotels.

Timing interacts with the number

Pool size assumes hotels can actually respond, which is a lead-time question. Send a 60-room RFP three weeks before the event and even a perfect eight-hotel list collapses, because half the city cannot take the block that late. Send it six months out and nearly every fit hotel can bid, so a tighter list works. As a rule of thumb: the shorter your runway, the wider your pool needs to be to absorb availability dropouts — and the more a two-wave structure protects you.

The two-wave tactic

If you are torn between 6 and 12, split the difference with sequencing: invite your best-fit 6 in wave one with a firm response deadline (7–10 days is the corporate-MICE sweet spot — tight enough to keep momentum, loose enough for revenue teams to price properly). If usable proposals come back short of 3, release wave two to the next 4 on your list the same day the deadline passes. You keep the focused-brief advantage with the wide-funnel safety net, and you never pay the twenty-proposal comparison tax.

What to do with the number once you have it

Whatever pool size you choose, three practices protect the value of it:

• Same brief, same deadline, every hotel. Proposals are only comparable if the inputs were identical. Our guide on writing the RFP itself covers the fields that make replies line up.
• Tell hotels the pool size honestly. “You are one of six hotels shortlisted for this programme” is a genuinely motivating sentence for a sales manager — it signals both competition and a real chance of winning.
• Score, then shortlist to 2–3 finalists, then negotiate. Don’t negotiate against eight hotels simultaneously. Rank the field (see how to compare hotel proposals apples to apples), take the top contenders into a final round, and drive terms there.

Five to eight qualified hotels, one identical brief, a firm deadline, and a two-or-three-finalist endgame. That is the whole formula — the rest of the value lives in how sharp your brief and your comparison are.
