We always go to Cosmo when we are there. He is the only one we trust. You can't miss him... he is always walking the beach in the yellow shirt and hat. It is $60 a person but he took $100 for two people.
Yookster - we wish we would have gone through Cosmo or Cosman...we rented jet skis through Elvis and will never do that again if we go back. It broke down on us about 3 miles from the resort and we were stuck out in the middle of the ocean for more than a 1/2 hour. We had been gone about 25 min and on our way back when it happened so they finally came looking for us after we had been gone for 60 min when it was only supposed to be 40 min. Then they wrongly accused us of hitting something or tipping it when we did neither. They were very nice up to that point. And we still had to pay them!
Both Elvis & Cosmo are solid men to work with. If anyone needs to see what Cosmo looks like, but really Yookster nailed Cosmo's description, go to Trip Advisor, get to Couples Swept Away, click on the photos/videos tab and you'll see a short video clip of yours truly w/Cosmo on the beach @ CSA! Enjoy your holiday in paradise! Razzl
