We rented a pontoon boat on 08/07/2015 all day for $300, not bad if you have a group of 8 or more.
The rental process was easy and fast, the safety check and boat check were quick and thorough. One new thing is you have to have a life vest on at all times in the boat. We thought it was crazy but it actually is not a big deal. It was really easy to swim and enjoy the lake knowing you didn't have to put too much effort into swimming and staying afloat. We had one problem when out boat didn't start, but we called the office and someone quickly came by to troubleshoot.
We will most likely return.
