We got one of these last trip, tried to use it and we were told that in order to use it, it would only be eligible if we didn't use our dining plan....in other words, the only person in our party that could have used it was my 2 yo nephew, because he was not on the dining plan and not using dining credits for his meal. Another thing, it is very limited...you could only get caeser salad, a burger, or pasta pomodoro. There is also a merchandise voucher, we got a free keychain, and if you do eat in the restaurant, they give you 20% off anything you buy.
