Simultaneous Interpretation in MICE & Hotel RFPs (Plain English Definition + Examples)
Definition
Simultaneous interpretation is real-time translation of a session by professional interpreters working in soundproof booths — attendees listen via wireless headsets and select their preferred language, enabling multilingual events without serial consecutive translation.
In day-to-day European event sourcing, simultaneous interpretation sits inside a broader workflow that includes the brief, the longlist, the shortlist, the contract negotiation, and the post-event reconciliation. Understanding it in isolation is not enough — what matters is how it interacts with the other levers a planner can pull. The definition above is the textbook version; the sections below explain how it actually behaves in real RFPs.
Why Simultaneous Interpretation matters
Simultaneous interpretation is mandatory for European institutional events, pharma global meetings, and any conference with mixed-language audiences above 50 people. Cost is significant — interpreter day rate is €750-1,200 per language pair, plus €400-800/day for booth rental and headset distribution. The lever is language scoping: covering the actual top-3 languages instead of 'all major European languages' often halves the spend.
Example
A 240-attendee pharma global summit needs EN-DE-FR-IT-ES coverage. Standard: 2 interpreters per language pair × 4 pairs × €950 × 2 days = €15,200 + booths €3,200 + headsets €1,800 = €20,200. Survey of attendee passport data: only 18 attendees needed IT or ES; planner drops to EN-DE-FR with on-demand consecutive for IT/ES — saves €7,600 with minimal experience hit.
Where Simultaneous Interpretation appears in contracts
Simultaneous interpretation is contracted via a specialist interpretation agency or the event AV partner. Always confirm: AIIC-accredited interpreters, booth ISO 2603 compliance, headset count (10% buffer above attendee count), recording protocol for interpreted streams.
When reviewing a hotel proposal or contract draft, scan for simultaneous interpretation early — it is often easier to negotiate before the supplier has anchored on their preferred position. Easy RFP surfaces these terms in every comparison view so planners can spot deviations from market-standard ranges at a glance, rather than reading 14-page proposals line by line.
