I forgot to mention, that on tripadvisor forums, I was reading that at certain places considered resorts or spas, that travellers would book through hotwire or a 3rd party, then get to the hotel and they would be charged an extra $15.00 or whatever amount per night for a "resort" fee. I would be so mad if I booked through a 3rd party, only to get there and find out that I would be paying another fee! Not sure how legit this is, but it seems to have happened to some people.
