We have only stayed at the Poly, but have visited and eaten at WL. We have 3 ds and I would definetely chose the Polynesian. Its our ds favorite. Interesting how your ds want the bunk beds. We had the bunkbeds at AKL and our kids said, gee we have these at home, we want to jump on a real bed!! The Polynesian has great restaurants, captain cooks for mug runs and snacks, ohanas, konas, mouseboast and bike rentals, great childrens activities, pool games, neverland club, great views of castle and ewp. Beach is awesome at night. My ds like to feed the ducks, look at the bunnies and feed the fish down by the marina. We have even done the family fishing trip. The monorail access cant be beat. Its great for resort hopping and we let our ds each have time at the contemporary arcade too. We are staying at the Poly next month too because of the great ap rate we got, I am cancelling our swan reservation because of that. My ds were so excited to hear they were going to the Polynesian, I even requested a volcano pool view again and I hope we get it. Good luck deciding. I should add my ds have played in the WL arcade and we ate at WCC. They didnt like it and thought it was too corny, but they are a little older than your ds. I do love the WL lobby, My dh actually fell asleep in one of the chairs after dinner while waiting for the ds to be done in the arcade.
