if you are staying in a disney hotel i would just buy the mug for your hotel. i bought one at AK i think it was, and it ended up being a pain in the butt. carrying it around it didn't really fit anywhere right. the one for our hotel i used alot and i will get it again for sure next time. a friend of mine brought some kind of brita waterbottle she refilled it threw out the park and had clean water, it worked way better than the mug she said . i am going to try it next time hope this helps have a great trip!:wave:
