DH and DD 13 went to it in July. I booked it for them because my DH cannot stand to jockey for a position for fireworks, can't stand people pushing their way in front of him, enjoys his own space to sit down, etc. Operationally, there were some issues with checking in (had to check in at two different spots and stand in two longer lines), seating (they hold the comfy couch spaces for parties larger than 2), and flow of getting the desserts (had to balance dessert box and beverage in hands while going through the line). The whole idea was for this to be a respite from standing in long lines, so DH was not thrilled with having to stand in not one, but two different lines. He and DD had to sit on ottomans and balance their desserts on their laps, they had no table. It was uncomfortable.
The pictures with Minnie were super cute, and I am glad to have them.
The overall experience did not meet their expectations. Once home, DH sent an email to Guest Services to share his experience so that management of this experience would gain knowledge of the guest experience and could possibly look to modify the check-in procedures and improve the flow. Hopefully someone who has done this experience recently will chime in and share details. My hope is that things have improved. If so, I would be tempted to try again on our next visit.
