Review for Riu Guanacaste Hotel and Casino Review For Riu Guanacaste Hotel and Casino Google User Mar 20 '16 at 15:42 Told us they would switch out rooms the next day since they are over booked fine no problem show up and they tell me he same thing they pushed to double beds together and called it a king and our toilet don't work thumbs down so far. Staff is rude when a problem is taken to them Had 4 rooms booked they placed on all different locations. Will up date as the trip goes on if they change. View full site to comment or like
