I have not, but we did the Safari Celebration Dinner and Magical Fireworks Voyage as part of a GG that I setup. Let me know if you need info on how to get the GG going.
We did Tony's Breakfast (Grand Gathering) Dec. 30/07 and it was wonderful. There were 9 in our group (5 boys ages 5-9) and two sets of parents. It started at 9am and the meal and entertainment was first rate. Tony (don't remember his actual name) is an opera singer from Italy and was amazing. The interaction with he and the characters were great. They give you special collector pins after the breakfast and then you are taken over to Philarmagic for a NO WAIT entrance to the show. We are already thinking about going again this year. We also did the Magical Firework on New Year's Eve and the Safari dinner. Our 2 boys enjoyed Ton'ys the most and I would have to say it was my favorite too. Hope this helps!!
