I think the studio and 2 BR concierge would be the most difficult villas to get as they are the most popular villas for booking. Since the 1BR still only sleeps four (or is five) many think that at double the points (or more) of a studio it's pretty expensive so many members get either a studio or 2 BR. So I think if you really want a concierge villa at 7 months you might have to go for a 1 BR.
