The website doesn't provide a whole lot of detail. Do your homework, buy tickets online. If you Google the right thing you can find better discounts. I got a family four pack for $110 +$3.99 processing. There are free life vests for use, on a first come first serve basis, lockers as well. You cannot wear water shoes on any of the slides. My kids 3 & 6 had a blast, there's a kids area for smaller kids to join the fun as well. There aren't any height requirements, and there didn't seem to be any limitations for anyone who had to wear a life vest.
