Pick a vibe — every category is a real page with reviews and booking.
Most escape rooms are limited to 4–6 players, so finding one for a large group is a classic organizer's headache. This page features rooms in Portsmouth that can actually accommodate 7, 8, and even 10+ people: large multi-room sets, duel formats where two teams compete, and venues that run multiple rooms simultaneously.
For corporate events and birthdays, call the venue after booking: many offer party rooms, championship formats across multiple escape rooms, and group discounts that aren't even listed on the site.
Practical tip: in a large team, appoint a "captain" to gather findings and keep track of time — with 8 pairs of hands, the bottleneck isn't the complexity of puzzles, but communication. Duel rooms solve this by splitting you into rival teams.
