I am heading down to WDW soon and plan on getting there early, then taking a boat to the Wilderness Lodge for lunch before heading to my resort to check in. I know that mugs are supposed to be good only at the resort you stay at, but can I purchase a mug at lunch and then still use it at my resort for the rest of my stay? It seems pretty silly if I would not be allowed to do this, but just want to make sure I am not breaking any rules. Thanks for any help or advice!
