If you want to stay nearby Freestone Park in Gilbert is great. Another place I know of that has paddle boats is Encanto Park in downtown Phoenix. There is also a kiddie amusement park there called Enchanted Island that is geared towards 2-8 year olds with carousel, train, roller coaster, bumper boats, plane, car & helicopter rides too. It's really a cute place. Here is the website http://www.enchantedisland.com/
