I agree with the above posters, in that you don't need to hop to be happy with young ones...they are happy where ever they plop down.
With that said, we are happy hoppers, and have used just about every pool in the complex, and I must say, they all have their benefits, and fun. We love slides, even the 4 y.o., and love to see their smiling faces as they come down. We really enjoyed Port Orleans and the French quarter, and the food court is right near by; have used Wilderness lodge and the kids liked the pool games they played there; Saratoga is great, food near by, splash area with Donald, small slide, plenty of chairs; In 44 days we are going to try out the Poly's pool...so we will have to let you know. Boardwalk's pool does seem to get conjested quickly, although it is nice to have a waiter come over and give you a drink; we have stayed away from the value resorts, as their pools are just large pools (have stayed on them before owning at OKW).
Hope this helps.
Have fun.
