We went with a group of 12 this past Nov. I planned and planned and things went at best "okay". It was A LOT more stressful than I had imagined. Everyone got along, which was great. But there are so many different personalities in the group. At one point I had my mother (50) ask me in MK if we could PLEASE do more "thrill" rides. I very quickly found out she was refering to things like POC and HM!! I was heading for the coasters. Also, people walk at so many different paces and someone ALWAYS has to go to the bathroom!!! I took all the advice from these boards mixed it with my past expierence and it still didn't go as planned. We had a good time, but I don't think I'll travel to Disney with a large group again. We camp all together every year and I'll stick to that. Another thing going against me was I had 9 newbies in the crowd!! We also did plan time apart every day. We always watched the parades together, ate together. As well as trying to hit up a few rides together.
