Thanks everyone. I am really torn. I know we don't want to do just a fastpass because it is predicted to be super crowded. With 2 kids, both the dining and dessert options are pricey, and my kids don't eat much, so it is basically a waste of money for them no matter what. We are doing the food and wine festival that day, so I am heaitant to book a big meals when we really are looking forward to snacking.
Leaning towards the dessert party. By the time I add up the cost of the dining package with tax and tip, plus us buying 2 sipper cups that we would probably buy anyway but will hopefully be included, I think my family would enjoy the dessert more despite the added cost.
