Are there washer/dryers in the rooms

For the more expensive rooms yes. If not, they still have washer and dryers on certain floors

It depends on which room type you get. If I'm not mistaken I think all rooms except the oceanfront deluxe double studio and the oceanfront deluxe king studio has washers and dryers. However they do have some you can use if you stay in those rooms. :)

Yes, but check the lint trap if you use the dryer. Ours looked like it had not been emptied in years.

Yes
