mugs, hmmm. I have NEVER used a mug at a different resort... however... we like to "resort hop". disney makes it SO EASY to do so,(they transfer your luggage) and it's a WONDERFUL thing!!! given our budget, we can't afford a whole week at a deluxe resort, but this way we get to try various deluxe resorts for a few days, and then transfer to a moderate or value resort for a few days. I think it is unfair for us to have to buy a new mug at each resort, when we are staying on disney property the whole time. being a stickler for rules, we just don't buy the mugs if we "resort hop"; we only buy them if we are staying at one resort for the whole stay. but I still say it is unfair... if I'm staying in disney, I'm staying in disney, not somewhere on I drive! If my luggage can be transferred, why not my mug? any thoughts?
