I'm sure somewhere in all of these posts someone has mentioned this but our favorite tip has to be....
DIVERSIONS!! We spent many evenings down there, until about 11:30 playing yahtzee and having a quiet drink. It is almost always nearly deserted in there... so a nice place to relax after a busy day.
During the day the kids can come with you and there are board games you can use. Our girls loved Jenga and yahtzee and Princess Chutes and Ladders. If you have late seating for dinner, this is a good place to come get snacks before your show. Around 5:00 they put out wings, tortilla chips with salsa, sour cream and some other toppings, fresh veggies and I think there were always hotdogs too.
If you are a sports fan they always have some kind of game on TV.
The waiters/bartenders down in Diversions are the nicest guys. Definitely set aside some time to spend down there
