Your souvenir/refillable mugs can only be used at the resort during the length of your stay. The parks do not have refillable mugs! - Jalex239  379.8 #7 2:37PM

Last time I was there you could buy souvenir cups at the resorts that were refillable at the resorts and water parks. - Grumps10  6.8 #260 1:44PM

I believe with the magic your way package you get a refillable mug but they only let you refill it at your hotel. Someone correct me if I'm wrong though... - Huskerkelsey  7.3 #246 1:44PM

Thanks everyone!! - dxcmama  176.0 #28 5:31PM

They will let u bring in reusable water bottles though. We did that. And I kept a bottle of Moo in my Fanny pack since not all of the water fountains are that great. Plus sometimes u just want smething besides water. But u can use Moo or the crystal light packets or whatever. It worked great for us. Thank u to the fellow mousewaiter who posted that suggestion, sorry, I can't remember who it was, but I appreciate it. - poohbr1205  13.6 #157 6:09PM
