Just one
CRITICAL thing about going late to Beaches & Cream, at least from the experience we had in October 2006. When we went there shortly before 11pm, we passed several cast members and were able, without anyone saying a word to us, to enter the take-out side. In front of us were 2 young (teenage, at a guess) girls who were being served by a CM (male, age 18-21 at a guess). He made their order, all the while we were standing right behind them (& should have been EASILY visible, after all, it wasn't like my wife & I are 3 ft tall!).
Unfortunately, after he served them & collected their payment, he turned to us and told us "We're closed" and refused to serve us.

Needless to say, we were VERY unhappy about this and discussed this with the front desk at the Beach Club. They agreed wholeheartedly that this was NOT how they felt that we should have been treated, and did what they could to make things "right".
Still, I would say that the take-home message is, give yourself a MINIMUM of 15 minutes before closing time to order, so you don't end up in a similar situation.
Enjoy the Magic, all the same!
