With the ages of the kids, I would pick a resort closest to the Magic Kingdom. We've stayed at both the Contemporary and the Polynesian. We won't go back to the Contemporary (don't care for the theme, the pool, the staff); we would go back to the Poly in a heartbeat. We had a great room, loved the theme of the resort, the pool, had extremely friendly staff and loved watching Wishes fro the beach. We've not stayed at the GF or WL as neither of them appeal to us in any way. Therefore, my vote is for the Poly.
