i must say I was dissapointed. The man at the window stamped my little card with a time and sent us to the boat dock. then the 4 kids were all fitted for life vests we were given our instructions and sent on our way.
We watched our time very carefully cruised down to DD and came back around. ANd you guessed it. They charged us from the time stamp the guy at the window gave us and that included the 15 -20 on the dock.
So the fee was double what i had figured it would be.
