Not only can you charge to your room key but any purchases you make (other than meals, obviously) can be sent back to your resort for delivery the next day free of charge. You won't have to lug your purchases around all day. The only day this doesn't work is the day before you leave since there's no guaranty it would get there before you check out. We've shipped small items like a little Darth Vader figure to big snow globes. They are delivered to your resort's gift shop. You need your green receipt and a photo ID to pick up your package(s).
