More relevant, Aquatica's only issue opening day was lack of chairs--was corrected within days. (Crowds became an issue quickly on local roadways, but that wasn't the park itself.) Haven't been to the LegoLand water park, but online reviews were positive when it opened, no horror stories on Touring Plans.
I wasn't in Florida during opening of Typhoon or Blizzard, but I've never heard horror stories. Is there still an archive of Rec.Arts.Disney? Should have been online reactions to Blizzard opening at least.
But the fact you're grasping at straws going back generations for apples-to-oranges comparisons is what really makes me ask questions.
