Children 4 and under are free. There is a playground themed room which we did as a family. My 4 year old loved it, but I agree that you would be very distracted watching a 2 yr old. I guess it depends on how many people you have and whether you care about escaping.

I would call and ask them. In Mission Mars you needed three people in different places to unlock things. Not sure if all the rooms have the same set up.

I would wear pants. There was one part of our adventure where one of us had to crawl. There is also a lot of looking for clues under and around things.

The website shows degrees of difficulty. I'd suggest choosing the easiest rated on your first try. Perhaps Underground Playground.

We played the Underground Playground at the East Iris Drive location in Nashville TN. The rooms are in the basement of the location.

Absolutely-it is so much fun!

Yes, they will most likely put you with another group

Depends on the children and their group dynamic.if they are willing to be serious and stay focused and are into puzzle-solving, they will. If it's a giggly or high energy group who would prefer to be running around, they might not. Know that the rooms are fairly small. I would rent the entire room for a group like that, otherwise you could end up with strangers in with you. Also, it would be helpful when you start to give a few assignments ("you two go through the bookshelf" "you look through the desk" etc). There was a group of boys about that age there when we visited. They were there for a second time and couldn't wait to try another room.

We did the terrorist one which had max of 6. One part has a tunnel to crawl thru BUT there is a wall that can be opened once someone has crawled thru to let those unable to crawl in the secondary room.
