Amberly:
With three boys in your traveling party, I think your second day needs to be spent at
Disney's Hollywood Studios! The children are the right ages to enjoy the Indiana Jones Stunt Spectacular not to mention
Jedi Training Academy. Although there are height requirements for Rock 'n' Roller Coaster (48") , Star Tours (40"), and Tower of Terror (40"), my guess is that the older two should be able to ride them all. Our youngest son enjoys the Muppets, and I bet yours would go along to Disney Junior LIVE for your daughter, just to enjoy some air conditioning.
Try and grab a reservation at
Sci-Fi Dinner Theatre, for just a slightly higher price than what you'll pay for counter service, you can get loads of memory-making entertainment for the bunch.
Wishing y'all a magical vacation!
