We LOVE the OKW GVs!!! We will be staying in one again in January with a total of 6 people, but we have stayed in one with as many as 11.
They are VERY spacious, and the master bedroom is several feet larger in one dimension than the 2 bedroom villas at OKW. Also, the master bath is a different layout with two pedistal sinks instead of one. Frankly, I think I like the bathroom layout of the 2 bedroom villas a bit better, but the GV one is very nice too.
The little hall bathroom on the first floor for any guests that might be using the living room is one of the cutest at OKW. It has interesting tile in it, and it is a 3/4 bath with a shower. I also LOVE the wicker table and chair set in the living room. There is a dining room as well that seats 8, but with that living room set, you can easily seat 12 for meals.
The only negative about the OKW GV is the kitchen. Somebody decided to put the sink jammed up against the corner at right angles to the stove, and by the time you put the island in there, it is NOT the most convenient kitchen to work in. You can't have someone standing at the sink and someone standing at the stove at the same time very easily. LOVE the location of the laundry room though. It's off the kitchen instead of the hallway, so it's easily used for storing things like bottled water and suitcases etc.
