I was at Orient beach on March 4th, I went to Kontiki beach club. The service, drinks, food, loungers were all great. Not a ton of sargassum, when I was there. The taxi we took charged $20 per person roundtrip for a group of four and waited there the entire time. We did get a couple massages from the roaming beach hawks, I did shoulder and back she wanted $65 I gave $50 and $100 for full body.
As for parasailing, on my beach walk, kinda in the middle of the beach,
was bikini-watersport dot com that offers parasailing. I can't really answer any question because I just walked by there location.
