We had a lot of expectations going into this room, which isn't a good thing, but it not only met those expectations, it exceeded them.
Absolutely amazing, immersive, and detailed set. Great puzzles, and hosting. Plus Air conditioning on a warm day was welcome.
The only thing I'd say is that they advertise it for up to 9 people, and personally I don't think it would be comfortable for any more than five or six. We were four people.
We were in Brighton on a bank holiday weekend, it was absolutely thronged. We parked in Churchill Square multi-story carpark (which Pier Pressure recommend) there were queues to get into the carpark, it was very tight if you've got a bigger car, and expensive. Maybe consider public transport. All that to say that it's worth giving yourself plenty of time to get there. The plus side being there's obviously plenty of places to eat and drink in Central Brighton.
