There's tons of fun stuff! You can rent bikes and boats. You can take a nature walk on the Swamp Trail. You can visit the petting farm and the stables where they keep the horses used in the parades and to pull the MK trolleys. I don't know how old your kids are, but they have pony rides for the little ones. You can have a great (and inexpensive) breakfast, lunch, or dinner at the Trail's End buffet. If you stay into the evening, there is the sing-along and campfire, which is TONS of fun! One thing we like to do is spend the morning at the MK, and then take the boat over to FW for lunch at Trail's End. After lunch, we enjoy all the graet things to do there before we head back on the boat to the MK. It's a great break from the park.
