No matter what you do, do not upgrade it is soooooo not necessary, Me and my 2 yr old went last year, he did not go hungry, and he and I our BIG eaters, I did bring water and organic milk,the ones that dont have to be refridgerated (just put them on ice), cereal bars, and crackers for him to snack on in the early morning(by the way they did fine on the plane in bubble wrap), I never paid for any drinks actually I was asked what does your son want to drink! and at PSB breakfast the waitress said she would refill his juice cup for us to take with us! if you are made to pay for his drinks whats a $1 or so a meal compared to paying for his park tickets,and etc.
