How did I manage the dessert party? Or how did I manage to sit for the show?
I bought tickets to the dessert party online. At the time they were $79 each and include unlimited alcoholic and non-alcoholic beverages, desserts, some snacks like fruit/cheese/hummus, priority viewing for the fireworks, and a commemorative gift.
As for the sitting part, I'm not sure if it's usual (because this was the first Star Wars dessert party I had been to) but when they led us out to our viewing area everyone just sat down and stayed sitting down the whole time. The spot for dessert party folks is right in front of the theater so there's nothing blocking your view.
