Sounds great. My DS may find your site before we do. He's a sucker for dogs.
We haven't started to plan out anything specific for the trip. My sister and her daughter are coming with us for their first trip to the Fort and my niece's first Disney trip. She's 5 now, will be 6 for the trip. Last weekend we were watching her and she announces, "I don't want to go to Disney World". I said. "You don't even know what Disney World is." I the pulled out the laptop and started playing Disney videos on the TV. She said, "OHHH!!! That's Disney? I WANT TO GO!!"
The only non-parks day I know of, for sure, is a trip over to the beach. My sister hasn't seen the ocean in over 20 years and my niece never has, so I told them we'd drive over to the beach one day. If my sister was a better driver, I'd let her take the truck over on her own, but I don't have that much faith.
