Hello! We are excitedly planning our family's first trip for October! About the mugs....I don't see what the problem would be, but wondering if anyone else has done this and gotten looks, etc....What if we bought 1 refillable mug...filled it, dumped it into our OWN mug, then went and refilled it again, dumped it, refilled it again...you get my point. If we take our OWN cups/mugs and just buy 1 disney mug and basically refill it several times to fill our OWN cups? Just wondering if anyone has done this? I like the idea of having free drinks at the resort, but know it will not be worth buying a bunch of them, but also don't want to have to run back to food court every time we run out!
