Exactly. The problem all the previous posters made was arriving to the park at noon.
Arrive to WnW at 9am and see what happens. You'll get on all the slides with no waits. Yes, it's early, but the reward is short lines for all the slides. Wake up at 7am and get on the move.
WnW is a great park. Get there early, do the major slides, then crash out next to the wave pool and have a few drinks. There's a beer stand to the right of the wave pool.
It's all in the timing of you getting to the parks.
Wake up early, get there before the gate opens.
