We did a GV at AKV Jambo House over Thanksgiving last year for a group of 10, and it was wonderful - like a nice house, and we were able to cook a big Thanksgiving dinner and all sit down to eat together at the table there. We also brought curtains with retractable rods, as well as an air mattress, and turned the pool table room into an extra room for the older teens to have a "room" to themselves. Myself and husband had the master, our kids had a bedroom, my SIL, husband and her younger kids had the third bedroom, and her older teens took the pool table room. (They could have slept in the living room, but they wanted their own space).
We have a GV this weekend at CCV and against at Jambo House, as we are taking our friends and their son (who is our godson) on their first trip, and we wanted to all share a space together. I can also give feedback on this weekend as to whether we thought it was worth it. We only have 6 people there this time (my oldest son is off at college now!!!), and while one could argue that we could have done this with a 2BR we didn't want to make my 15 year old sleep in the living room when there is going to be a toddler waking up at 6am. We opted for the GV to give us plenty of "living space" and to ensure that everyone (us, our son, and our friends & their toddler) had their own room. Yes, it was a crazy amount of points, but this is a special trip as it is our godson's very first and we wanted to make it wonderful, special, and easy for our friends.
