The current plan is for 10 days (not 7 like last year, not LOS like the year before that) for $255 (not $199) and is good for up to 5 people.
This CM was on Crescent Lake (Y&B / BW). When I asked him about minimum requirements for driver's on the water mice, he said that they hadn't changed. I asked, since I had read about the accident at Bay Lake (CR / WL / GF / PL). He said he had heard about the likely change for Bay Lake to a minimum of 16 years and/or driver license, but he wasn't sure. Suggested calling that marina directly, which I have not done.
To reinforce prior poster's point, you should probably call the marina where you want to have your plan and ask all your questions. If you start with the number she provided, you can make you way through phone triage to the marina CM you are looking for....
