Psh I want a lazy river!!! Sure I'm not in that club but man who doesn't love a lazy river? With correct theming and length it could be the crowning jewel of the park like adventure island. Universal could definitely make the best lazy river ever if they applied tons of theming, maybe like the people mover where you could get a glimpse into other attractions like the Volcano maybe? A wave pool would be nice tooI think lazy river and wave pool is a must among the core group of people who go to waterparks - That is not us, we would be open minded to not having a lazy river or wave pool, the other 99.7% of the world will criticize the park for not having those things...
But that doesnt mean they cant be innovative!
