Golf cart is not necesary but we love it. You can go to the Meadows for all the recreation easily, grab something from the Trading Post, or pick up a Giddy up and Go takeout bucket of chicken! The cabin pool is very nice and basic (no slide) but there is a hot tub. We never have a problem getting a table with umbrella there.
The main pool is very nice. I'm not sure when PP stayed there, but the slide is not a basic one any more. It has a big water tower with a curly slide, a nice kids splash area and a great snack bar/food options.
Definitely go to the Chip and Dale sing-along and movie one night (once again, golf cart is great for that). You must also hit the beach for fireworks and the Electrical Water Pageant (at 9:45 every night).
We bought cheap seat and table cover set for the picnic table and used that mostly, but we've also brought the bag chairs for more comfort.
The beauty of the cabins for me is that there is no one sharing any walls with you, so you don't hear footsteps, conversations, flushing toilets, showers, yelling or babies crying. If you have a little one, you don't have to worry that someone is being kept awake in another room by a crying baby at all hours of the night. And the nature, and the peaceful feeling. It's absolutely beautiful.
Dh and I would stay there every time, but kids like to move around a bit. For the price and the amenities, the Fort is the best!!!
