Marshmallows are provided. I did the bonfire at Riverside, but it's the same at all the resorts. They even provide the sticks. You need to buy your own smores though if you want that.
These are from Port Orleans Riverside, but the activity is the same if not the actual bonfire.

And the pool has a waterslide, plus a little hottub nearby. I don`t have recent pictures of POFQ because it`s been a while, but I`ll go in 10-20 days and take some pictures.
I love resort visiting.
