I beleive it is yes to the 1 dessert on the CS meal. The item up in the air is what are our choices with using the refillable mug instead of the drink option.
Thanks for the warning about the tea, I prefer fresh brewed anyway.
I know last year (Feb. 08) we had several meals on the deluxe dp left and we were able to get 3 snacks for each credit left. We didn't have to eat much real food on our drive home.
