We are going to the RIU Guanacaste in May. Does anyone know the RIU's email address so we may send special room requests? Also we are thinking of renting a car and driving to Lake Arenal. We will probably rent a room for the night in the area so we won't be rushed or have to drive in the dark. Any recommendations or suggestions? Also could someone recommend a good private tour company? Can someone recommend a top notch deep sea fishing charter company? And one more question - we are taking my parents who are not in perfect shape - what would be a fun tour to take them on?
