You've already gotten good information on the pony rides, although I'm pretty sure the price has gone up to $4. As to other things at FW - when my kids were younger, they liked to play on the beach, go into the horse stable next to the petting zoo and look at the big horses, and wander around the settlement area. One of their favorite things was looking for lizards - they always had good luck by the horse stables at the Outpost, and these days there are tons of them in the cleared areas behind the various loops. They have carriage rides in the evening. You could rent a Sea Raycer and take the little one for a spin on the lake. Or you could hop the boat to the Wilderness Lodge just for fun - I don't think AKL has boat transportation, so that would be different. At WL I think you can rent surreys - I've seen them on the path between FW and WL. And of course there's the campfire program and movie.
