We have done BBB at MK several times, and It is fun, and there's something super magical about getting your hair done in the castle. That said, I felt it was crowded and I felt a bit rushed (the first time we went), especially when choosing a costume. Since that time we go to Castle Couture before the appointment and pick out our costume at a leisurely pace. We have not done the BBB at GF, but we did do the Ivy Trellis last visit before it became the new BBB (see my avatar) and it was a great delight. We plan to go again this visit. We also followed up our appointment with dinner at the 1900 Park Fare restaurant with Cinderella, etc, and if it's the right day, you can observe Cinderella and the Prince come down the grand staircase and do a dance before entering the restaurant. When we do the BBB at the MK we have lunch at the castle afterwards. Both were fun. Not sure if the atmosphere at the GF is any different since it changed over. After our dinner at Park Fare we went over to MK for the evening. Great fun!
