I think the waterpark would probably reduce lines by quite a bit on warm days. For cold days, a person would probably wait as much as they did last year. Waterparks take a lot of people, believe it or not. With 25 attractions, I would expect that to reduce the lines.
^That is, if everything stays the same. By this I mean, that all flats and rollercoasters will be operating like they did.
This could happen though:
Waterpark=more employees=more money
thus
Regular Park=less employees=less rides running
So, it all depends on whether the rides will be running like they did last year. If so, it should significantly reduce people in the park.
