I was told there's activities for kids some of which cost extra, can you tell me more about these and how much

Its different every day/week for example memorial day weekend we had tye dying tee shirts candy bingo and a few others i forget and they cost between 5 and 20 dollars depending on what activity it is some are free

I'm not sure how much it cost but I believe there's three wheeler bike rentals and of course the water attractions
