We've parasailed with Roberto's Watersports before and would definitely recommend them. We didn't go last year but we'll be there in 9 days and we'll look them up again! I can't exactly remember where on the beach they are but I'm sure the concierge at your hotel could tell you. We stayed at the Marriott Stellaris then so I'm thinking it was up the beach from there (back towards the other hotels....Stellaris is the last one on the end). Good luck and have a great trip!
