DS(13) and I always travel with one or two of his best buddies & their parents, both family friends for 10 years +. Thankfully we all like to vacation the same way so it's been really wonderful to share our DVC with them. I always book 2brs to ensure that we are all comfortable.
Also, we host a family reunion every 3 years or so, where we are between 9 and 11 family members, so it's an OKW GV for those occasions. 2012 will be the 4th time, we have family from France, England, Tennessee & New York. None of this would be possible without DVC, it's been a blessing!
