Don't know what your budget it, but see you want somethig that will last the better part of the day, so how about fantasia mini golf, just get a bus to swan/dolphin and walk across the street, then go back to boardwalk for lunch at espn zone, and then use the swan/dolphin bus to go to dtd for either disney quest or a movie, hmm either place is good to get a nice rest and air conditioning break. That should take up till about 5 pm maybe. The fishing trip is expensive though. The later times are cheaper. They could just do cane pole fishing at old man river at por I think, have never done this though. The boats are fun, but dont last long. How about a water park.
