We just concluded a trip in early December that, at its peak, included 14 people. We had different arrival days and were spread at various resorts, although 12 of us did share a GV at OKW for four nights. While there we did an early Christmas celebration (had a tree, decorations, etc.), and cooked one meal there as well (our traditional Christmas prime rib).
For the most part, people went their own way during the day. A couple of times we met up for meals (all of us at Tusker house one day, and breakfast at Ohana another day). We had one person who was on his first trip to WDW, and another couple from CA who are Disney fans, but had only been to WDW for a short trip before. That worked out well, since more experienced folks served as "tour guides". DW and I pretty much served as coordinators, making sure people knew which parks had EMH, what times the fireworks shows were, and so on. When the time came to move into the GV, we took care of all the luggage transfers, and also did some airport running for later arrivals and early departures.
I will say, however, that our most fun evening was one where we were all together at DHS. Our CM daughter had, the year before at a cm closeout sale, bought a bunch of Mickey Ear hats that had reindeer antlers on them. We had enough so that 10 were wearing those, and 4 others were wearing Goofy or Mickey Santa hats. We took some great photopass pictures, took in the Osborn lights, went on TSM -- just had a blast enjoying the Christmas atmoshpere and being silly. We even overheard other guests, upon seeing our hats and such, saying things like, "They must be drunk!" We weren't, but we did kind of feel a bit of a natural "high" just being together and enjoying the whole atmosphere.
For next year we plan on an AKV GV in early December.
