Marriott World Center has 2 pools, a splash zone, and 3 waterslides that are pretty fun. I was just there last week and thought it would be fun for that age group.
Our waterslides here (at the Jersey Shore) aren't as restrictive on height, so I was caught short on that. It really stinks because he's been a USA swimmer for over 2 years, and surfs, so it's not like he's unskilled in the water... we're a little bummed and I pre-paid. 
Hey Guys well i think that there are many hotels are available including the Pools but having not slides.For that the golden nugget is really Wonderful.Look it up online i went there and my kids had a good time.Thanks!!
Unless you have a short 7 year old. Mine isn't 48" and we're booked for Sept...![]()
Our daughter is 8.5 but is in the tenth percentile for height. She is a great swimmer but was held back from the water slide as she is only 47.5". There were 5 year olds using the slide and many who didn't get measured that appeared smaller than her. The Fountains (Blue Green) did not have a restriction. Not sure if the slide at Marriott Harbor Lake is very thrilling but we may try that one next.Thank you for pointing this out. Does anyone know if this height limit holds true for all of the resorts listed so far? My 6 year old is not tall, but he is a good swimmer!
