They are supposed to. Last year I brought one and ended up loaning it to someone that didn't have one in the room. I assume if yours is missing, housekeeping can bring you one. Have fun.
Last trip, room had a hair dryer. Some will tell you that it's awful and bring your own, but I found it to be ok...and I have big hair too!
They have the really small ones. I have long curly hair and have to use a diffuser, which doesn't fit on a hair dryer like they have, so I always have to bring my own. Takes up a bunch of space in my suitcase, which I hate, but my hair would be a mess otherwise. Everybody thinks naturally curly hair is wash and wear like a perm - I assure you it is NOT! But if you need a powerful blow dryer, you will not like what is in the room. My hair is so think that if I tried to use it to straighten my hair, it would probably take 90 minutes with that dryer!!
their freaken noisy and slow too ,,, I have to leave the room and by the time she's done,, Lulu has done me in too with her great Tequila shots.
