I am going parisailing for the first time in October during one of our port of calls. I actually did some research on this and the cruise I am going on isn't offering any excursions which consist of parisailing. The last port of call is Aruba, which I've been to before and just love, and on Palm Beach they have watersports located on the beach that offers just about any water sport, especially parasailing. Let me know what islands you are going to and maybe I can help you locate a independant watersport company on that island if your cruise isn't offering any excursions with parisailing. If you are traveling to Aruba you can contact Unique Sports that offer parisailing and their telephone number is Tel/Fax: (297) 586-0096 THEY ARE LOCATED ??
On the Beach of Palm Beach between Radisson 4 Diamond Resort and Riu. Our boats leave from the pier in front of our shop. We also provide free of charge hotel pick-up service if you are staying in other fine hotels.
If I can be of any help please ask and I'll try to help you. Happy Crusing.
