Just a quick reply - got home late last night and are still trying to find the house, laundry, etc!
We did the party on Friday as well and thought it was well worth it. I do have pictures, but they're not on the computer yet, and really, not that good with my cheap camera. I've seen a lot of pics and everything was as described. We probably would have enjoyed it more if we hadn't had 'Ohana dinner right beforehand, but still managed to eat our share of desserts!
We had a nice table that we shared with another TGM'er, right in the first row. We could have easily sat at our table for Wishes, but opted to stand at the rail. There was plenty of room and I don't think anyone felt crowded or had trouble finding a space. The tables were quite tight but they appeared to be fixed so that's just how they normally are. I never saw any shortages of desserts - yes, there were sometimes gaps, but they seemed to be filled quickly with a new tray.
We went primarily to meet others and there were many parties of TGM and DIS'ers. For anyone else there, my son was the one in his DIS shirt handing out small flashlights and glow light bracelets to all the kids! I ended up just sitting and socializing and missed meeting a lot of people. There was plenty of ice and the drinks were cold and the snacks were all good and cold. Liked the mousse desserts and the fruit (which seemed refreshing in the heat). Sorry, but all of us at our table thought the Mango Shooters were HORRIBLE! They looked so good but were way too bitter for us.
Check in only took a couple minutes - maybe 10 people in line ahead of us when we got there around 8:05 for our 8:15 time. Just long enough for them to check the list and put on wristbands. Food was all ready and there were never lines at the buffet that I saw. The castle was beautiful there and it was a lot of fun. With two of us I think it was definitely worth it and a great time. I probably wouldn't do it again, especially with a family of 5 and the new, higher cost, but we wouldn't normally do Wishes at all since we're definitely early to bed, early to the parks folks! If you plan to do it anyways, it's much better than sitting on the curb for an hour and the view can't be beat and the food is just the added bonus!
I'll be glad to answer any specific questions!
