I worked at this park as a part time job in High School for about three years. I have gone back since then, and though management has changed somewhat, the park itself hasnt gotten much better.
First off, lets start with the good.
WildWaves is an outdoor waterpark in Washington. You're going to have to be okay with the fact that you might get rain while you're there. If you go on a rainy day, a plus is tahat the water rides are still open (as long as theres no thunder or lightning) and theres usually no lines and warm water temps. Avoid going on weekend with hot temps if possible, it will be REALLY crowded. Go during the week. The park has a waterpark side and a rides side, which you have access to both. With only one park enterance, its a little easier to let your kids run around and have fun while you relax (as long as theyre old enough not to go home with strangers). Its a great park to visit in the summer, you can spend all day here, and completely tucker the little ones out.
The park needs shaded areas. While they do have some cover over ride ques, I remember tons of instances where guests passed out in line from the heat. This might be partly from them not hydrating, but an easy way for the park to keep guests cool and to minimize emergency calls is to spend some money in misting stations throughout walkways or shaded areas.
You have to choose between dropping at least $15 on a locker, or risk leaving your items in the open and get them stolen. Dont think that just because its covered with a towel, or you tucked it in a corner that it wont get stolen. It happens everyday. Lock it in your car or buy a locker. It would be nice if the park had some sort of way to pay without needing your wallet, like a wristband.
The bathrooms. They're disgusting. Avoid changing your kids in there, avoid showering in there, and just avoid them if you can. The ones on the dry side are cleaner, but the bathrooms by Hook's Lagoon and the arcade are the worst in the park. Wildwaves hires High School aged kids to clean their restrooms. If they cant keep their rooms at home clean, what makes them think the kids want to clean a public restroom? This problem will probably never be fixed.
The Food. I have been visiting this park since I was a kid, before I worked there. I had a season pass every year, and they have had the same food, plus a few more artery-clogging options, since I can remember. Dont order the food. Its all fried, pre-frozen, and processed.
I suggest bringing a lunch and eating in the car, or leaving for lunch. Theres a walmart nearby where you can buy healthy options (or anything else), and the Crossings has tons of restaraunts such as Blue Island Sushi, Panda Express, The Rock pizza, Etc. Youll get a much better value, and its not overloaded with salt.
Overall, I say visit the park. Leave your items in the car, pack a lunch, dont buy the food, and use the bathrooms on the dry side. And be nice to the lifeguards, and WALK, dont run!!!!
