I did it just this past October. It was really great, though because of the timing we made the mistake of letting it replace dinner. I would NOT do that again, though with it starting at 6:30 (8 PM show) it was hard to time. Thankfully they did have some pita, hummus, and olives and cheese skewers in addition to all the sugar, which was a lifesaver.
Anyway, that's my fault. The event itself was excellent. I had never done a desert party before, but I loved how they made us feel like a VIP with our lanyards and big passes to the event. The selection of deserts was great, especially the flash-frozen Nutella truffles. There was so much I don't know that I even tried everything. It was really nice to have the private area, though meeting the characters was still open to the public so the wait times were still long. We were escorted to our viewing area by a couple of Troopers and we had a great spot to watch the shows. They also gave us TIE Fighter popcorn buckets to take with us. Overall, we had a great time!
