We strongly recommend that you do not exceed 8 people in thei room as it may take away from the game a little bit because there's only so many puzzles in each room. We have had groups as much as 10 in one room but that does make it easier to escape. I hope this helps
6 people is a good size group. My last group had 7.
Yes, you can.
