We stayed in a grand villa in 1996. We were traveling with our son, my in-laws (MIL, FIL, BIL), my parents and my husband's cousin and his wife. The grand villa is bigger than my in-laws house, so we had plenty of room for everyone to spread out. It was the first Disney trip for my parents & DH's cousin and they were beyond impressed.
We used the kitchen just about every day for breakfast and occasionally for dinner. It was nice to have the dining room, and the laundry room was great, better than the closet you get in the newer units. OKW just feels like a country club to me, and staying in the grand villa just made us feel really special!
