I had decided not to do the dessert party...and then saw it was available for my big Star Wars day and heck, booked it. I've only ever done the HEA dessert party, and "worth it" is a tricky question--I personally wouldn't do the HEA party again, but there were enough things I liked about it combined with some things at the Galactic Spectacular party that sounded better that I decided to go for it. I'd like to see the Star Wars fireworks, since I haven't seen them before, and not having to show up early and not being jostled or having people blocking my view during the show is great. Whether it's $89 worth of great is debatable, but the Galactic Spectacular party won me over with a few things the HEA party lacked:
1. Better themed party area. The dessert party at MK felt a bit bleak to me, tbh; Tomorrowland Terrace is not a particularly inspiring location. The images I've seen of the Launch Bay seating may not be hyper-themed, but the addition of roaming stormtroopers and better-themed food displays tips the balance.
2. The inclusion of alcoholic drinks. Figure you'd be paying $12 per drink anywhere else in the park, and figure I'll probably have two drinks, that's $24 out of the $89 right there. Compare it to the cost of a buffet dinner with two alcoholic drinks and it's surprisingly comparable--and I do view this as a dinner reservation, because--
3. The inclusion of savory options. Having looked over reviews, menus, and photos, I'm confident I can get my fill at the party without going into a sugar coma from eating nothing but chocolate.
The cost is still high enough that I find myself going "did I really book that??" but I've decided to view it as an indulgence worth doing at least once.
