Can a group of three people go or does it have to be 4 people and up?

We've done 3 its a lil tricky but possible

3 can certainly do a room Sarah. We suggest 4 as a general recommendation - but we often see groups of 3 or even 2. The thing to remember is the fewer people you have the more challenging it can be to complete the room before your time is up as there aren't as many people to help solve the puzzles - but it isn't a rule. Hope to see you there.
