Hi there, Kimberly!
Probably the best way I know to wind down after a day of travel - or a day at one of the four Walt Disney World Parks - is by hanging out poolside. The water temperature is always excellent, and you can relax in the shallow end or the kiddie pool while your children splash happily about. Many of the Resorts on Disney property do offer refreshments poolside, so light snacks and cold drinks await you.
Some Resorts also offer movies at night; you will want to check with the Cast Member who checks you in to see if your Resort is one of those.
If you want to travel just a bit, check out
Chip 'n Dale's Campfire Sing-A-Long, located in Disney's Fort Wilderness. This complimentary nighttime experience brings comedy, music, and a film to your family. Refreshments are available for a nominal fee, or you can bring your own. S'mores are encouraged.
If you'd like, drop me a line with your home Resort, and I'd be glad to provide more specific suggestions. I hope to hear from you!
See you later, celebrator,
-Deborah B.
