I've never seen any, and with a friend whost two children are allergic to milk, I always seem to look for her, even though she isn't there. I can tell you that there won't be ANY in the parks, and most likely none in any of the resort gift shops. I'd suggest going to one of the many close grocery stores and buying your own. You can rent a fridge for $10 per day to keep it cold and then just bring it with you into the parks in an insulated bag to keep it cold and fresh. We brought those playtex insulated sippie cups for DS milk, and in the cold pack, they stayed VERY cold and fresh!!!
