Hi Dana!
Sounds like you have a lot of good stuff planned already!
If you have 10 day tickets with water parks, I'd suggest you play one day, then rest the next. There are so many fun things to explore outside the parks. You can go mini-golfing, shopping at Downtown Disney, visit some of the hotels (you can book some good meals here, too!), ride horses at Fort Wilderness, rent bikes at several resorts or just play at the pool of your own resort!
And another thing I love to do is just get prepared--look through allears.net, a Disney guide book or even the
Let the Memories Begin page. You'll get great ideas for the attractions you want to see, places you want to take pictures at and things you don't want to miss.
If you have any specific questions,
please ask me directly! I'd love to help!
