Planning a trip to the Roc Museum of Play- tips?

Court0026

Any tips?  Unfortunately, we are going on Saturday.  UGH.  I went once about 10 years ago in college while I was babysitting for a weekend.  It was a holiday weekend and I took a 2 and 4 year old by myself and basically just barely "lived to tell about it".  LOL.  They had been there before and literally tried to run as soon as we got there.  Newb move. 

Anyway, we are meeting my sister and BIL who live in Buffalo so they can see the kids in action.  My big fear is always the food allergies.  Bringing lunch and hoping kids aren't walking around eating pb&js!  Anything I should know?  Thanks!
