I think my wife used a hair dryer, yes.
Yes, there is a blow dryer in the Cosy and the Snug rooms. I think they were in the desk drawer. Just a tip one of my travel companions had a heck of a time finding the plug in the bathroom, it's on the side of the mirror, kinda behind it.
There's a hair dryer in room, and the front desk will get you anything you want. Also free bottles of water - unlimited, so no need to go to store to buy.
