I called priceline and they called the hotel. The hotel told priceline that the resort fee was charged to all guests. I knew this was BS so I called the hotel and was told that if you book online at Radisson.com there is no resort fee.
I bid on priceline for 4 stars and won at $87. This hotel is not 4 stars. They also charged an extra $9.60 surcharge because I paid via priceline. I was not notified beforehand. Be careful bidding on 4 stars in San Juan.
