It is only a launch away instead of the monorail but I really like Roaring Forks at Wilderness Lodge. It has been way too long since I have stayed to GF and Contemporary to even know anything. I think the counter service at Poly is decent?
Anyway, I suggest taking a launch to WL and eat there. Great atmosphere with the waterfalls, relaxing boat ride, and good food.
But I bet someone here can give you good advice for the Monorail hotels.
