About a $25 trip from Waikiki by ride share. Staff, especially on the boats, extremely polite, kind, and helpful.
We did the jetski and parasailing. For jet sking you do a ride,or race, around a route marked out by bouys. But I still thought it fun.
For the parasail part the BRIEF 6 minutes you are up it is astoundingly wonderful and beautiful. But all so brief
The GoPro pictures you must purchase if you want a digital memory of the trip as you can't take your own cameras for the excursion. I too think this is too expensive of a service
So a very fun time. Dollar to dollar is it worth it You have to decide.
