Loved them! We drank gallons of coke while we were there. We were allowed to bring them into the parks, too, so it was nice to stroll to Epcot sipping our cokes and continue on into the park with them. I was so spoiled to not paying for my coke that I didn't get soft drinks in any of the restaurants we ate at because I couldn't stomach paying for them!! I didn't have that problem with anything else, though, judging from the size of our checkout bill.
