I have been and my daughter(16) has been several times. Wild Waves is not a destination park, IMO. It is not something that I would make a trip for. I am not very happy with the cleanliness of the park and it is overpriced and understaffed. You can spend forever in line trying to buy a drink. You will hear lots of foul language. A few years back, Six Flags bought this park, then quickly sold it as it just didn't meet Six Flag standards and they didn't want to spend the money it would take to bring it up to snuff. Not sure what sort of trip you are looking for or what are the ages that are in your group? If you have teens I would head toward Silverwood in Idaho (not too far from Spokane). It has a waterpark and larger amusement park with coasters. If you have younger kids, I might think about the Great Wolf Lodge near Centralia, WA which is an indoor waterpark/hotel. You have to stay at the Lodge to use the waterpark, but they will let you use it all day on check-in and check-out day. Ask if you have more questions.
