We experienced the after fireworks party on Thursday, 6/7. Fireworks time was 9:15pm with an 11pm park close. We had not previously done a MK dessert party so had nothing to compare it to, but we did not find the garden overcrowded at all. There was substantial rain leading up to the fireworks, ending about 30 minutes before the show, but the crowds remained heavy outside of the viewing area. We checked in about 8:15, received our wristbands, and ended up sitting in Cosmic Ray's for a bit (our choice as the ground was soaking wet and it was still drizzling), prior to returning to the viewing area at 9:00. When we checked in, they were also handing out ponchos to those who didn't have them already, which was a nice touch. We had a great view in the center of the garden, about halfway back. The pre-party tables appeared full when we checked in, and the after party tables were about half full. Following the fireworks, it was an easy trip back to the Terrace to grab our desserts and relax a bit. One thing I didn't think about - you obviously cannot see Once Upon a Time from the tables, so we wrapped up our desserts a bit earlier than planned (although we were basically done), as we wanted to see the show. Overall, we really enjoyed it, and would definitely consider doing it again.
