Yes, if you do a larger room you may be put with another group of people. But totally!
We were a party of six joined by a couple we didn't know. I don't think we would have "escaped" without them. Have also been a party of just four during mid afternoon on a weekday.
If it's a slow day, you should be able to have the room to yourselves. The only way to be certain, is to buy a whole room for the group. Something else to consider, we've had fun working with together with an unknown group to complete an escape. :) Have fun!
Absolutely! I've been there with a group of 6 all in one room. Great fun.
