I'll start off saying, we have been to both but not recently......many trips ago....they are fun, huge, sometimes over crowded and tiring and expensive....plus they eat up a day.. No way would we go for just a few hours.....financially wrong....We never get the "and more" on our tickets since we might only do one waterpark but we find the crowds, finding a lounge, and general pain in the neck of doing one....not worth it...we get just as much mater, fun and cooling off at the resort pool, plus our room is right there, easy to restock our cooler and relax....
It seemed the last we were at a Disney waterpark, we spent more time waiting in a line than actual sliding and to spend that kind of money to lull around the wave pool or lazy river, just was not worth the effort....sorry, but we skip them anymore....but if we do decide to go again, we'll just pay out of pocket for the one time than adding on to our tickets...
