we only paid for one person on Viator, It says 30 min included, and when We got there they wanted to put in only 15 minutes of ride, because They said it was for 2 people and We only paid one, but on the purchase said 30 min included even for 1, we waited 2 hours at the place for him to be able to ride the jet ski, so long waiting, long list, without even having water to drink. So long time 12 to 3pm. There was nothing to drink on the waiting boat, no water, full of people, no space to sit, some workers were helpful and others look like they were also tourists, camera guy and organizer was the best workers.
I don't think is a good way to spend a day in Hawaii.
