Yes, each villa has a hair dryer. Like BeccaG said, it is in a labeled black back in the bathroom.
Btw, I spoke to my guide while I was at DLR last week and he said there is a growing waiting list for VGC. 120 pp, no incentives except for points from 2010 if your waitlist comes through before your desired use year month is passed. They are trying to push SSR with 99/pt. He talked about being able to book VGC at 7 months with the SSR points, but we decided to waitlist VGC instead and are considering Aulani.
This was also our first time in a studio and there were stains on the chairs and the sofa was badly frayed. We couldn't open our patio door the last night because the people above us were smoking quite a bit on their balcony and the smell/smoke was very strong. We notified the front desk but we checked out early the next morning so I don't know what came out of it.
