Also at SSR, in the Grandstands section, they have a great water play area for the little ones (they have a nice pool and spa located there too). http://www.allearsnet.com/acc/ss218.jpg
Poly
Beach Club/Yacht Club has a nice sandy beach area in the "Quiet Lagoon" section of their pool which could be considered zero entry. Your 2 year old could play in the sand and the water. http://www.allearsnet.com/acc/sab15.jpg
