I had never been parasailing before and was very excited to try this out in Hawaii. Their booth was a little tricky to find, but I called them with my location and they gave me good directions to get there (they can also pick you up at your hotel for free).
There were 5 people on our boat, plus the crew (Kevin and Russell). I was the only one from my group, and ended up going up with another couple on the boat. I paid for the 500ft line, but since there were 3 of us going up, they let us do the 1000ft line, which was a nice touch. It was a little scary going up, but once at the top, the views were absolutely stunning. It is so peaceful up there, with ocean as far as you can see. Just beautiful!
They can take pictures of you if you'd like, and then you pay them for the memory card (they take about 90 pictures and it's $30). I just traded with another couple on the boat - I took their pictures, they took mine. Turned out great! Overall, wonderful value and great experience with this company.
