We bought the Captains plan at the Poly one year over a long weekend while we were staying at Shades of Green; 6 hours for the price of 4 decided up how you wish; 3 sprites for 2 hours, 2 four 3, etc. We had a cast member who decided not to keep track or deducting 30 minutes when it should have been 3 hours. We drove for free all weekend. Monday came, a new crew and that was the end of the free ride. Exhausted our plan of 3 boats in an hour.
