No, you cannot pool hop. Pools at each resort are for use by those resort guests only.
That benefit is only for DVC members, and they are even restricted to where they can go. For example, Stormalong Bay at the BC/YC and the AKL pool are for THOSE resort/DVC guests only, and NO ONE ELSE, including DVC members, may use them.
Discussions about pool hopping are discouraged here, by the way. It's against Disney's rules, so some people might come on here and try to tell you that they "do it all the time", but those posts will be deleted and the thread will be shut down if it goes in that direction (just giving you fair warning).
In my opinion, the best pools are:
-Stormalong Bay (Beach Club/Yacht Club)
-Wilderness Lodge
-Caribbean Beach (from the pictures I've seen...brand new pool looks awesome!)
