We had Disney move our bags from the Poly over to Pop on one trip, and had no problems at all. We called the front desk, and they sent someone to pick up our bags from the room(we did tip him a few dollars). He tagged them in front of us, and told them they should arrive in 2-4 hours. We left, went to a Charachter breakfast and explored a new resort before heading over to Pop. I would guess that we got our bags in about 3-4 hours. It was really easy and care free....which was such a relief to me because I was really worried about it! I would keep a small bag with you with anything you may need-medications, cameras, etc.
