Single with 340 points. I go by myself, with friends, or with family. I have taken family for 10 days in a GV at OKW--I had other friends and family in studios for 2 nights--to celebrate my parents' anniversary. I have taken my mom for Flower and Garden Festival, each of my nieces separately, and another friend who had never been to WDW. My best friend is a DVC member, too, so we have combined points from time to time.
While every trip has been unique and enjoyable, and it is fun to share WDW with others, I probably enjoy going solo best because then I don't feel responsible for ensuring everyone has a good time.
