We've had annual passes for 4 years and this last summer will be our last. The line management is poor and the park really is in need of beautification and maintenance in its off season. We did really appreciate the upgrade to the Cactus Cooler (lazy river) and it made the ride so much more fun and enjoyable.
WnW really needs to address a sewer problem by the bathrooms by that ride - they SMELL first thing in the morning and only get worse as the day grows longer - and if there is a breeze blowing in the wrong direction - you get the foul stench when sitting in the shade in the chairs.
Is it expensive? Yes. But if you go at least twice (we go 4-8 times over the summer) it more than pays for itself.
