We had the WPF&M option last trip (April 2008). I think our whole family (DS5, DD7, DD10) loved the water parks as much or more than the regular parks, and also loved the virtual roller coaster in DQ. If you go twice, you're saving money (it's cheaper to buy a single admission than the WPF&M option). We went 4 times, would've gone more - probably would next time. We liked the wave pool at TL better than BB, but both were great.
