I know the big pontoon boat was 45/half hour plus tax.
We had some pixie dust last trip, the kids had the Jester cruise scheduled the one day, well we show up at the time they told me, and apparently it was the wrong time. Well, the CM at the marina felt so bad, he got us rescheduled for a few days later and then gave us a big pontoon boat for an hour for free, plus a few drinks as a way of apologizing. It was awesome!! The hour gave us time to drive all the way to DTD and around the lake then back to POR. It was very relaxing and we would pay to rent one in the future we had so much fun!!
