We went on the second Saturday after opening, while the park is still open for season pass members only. We arrived around 4:00 ish The first thing that was nice was that we didn't have to pay for parking even though we didn't have our passes yet. We just told the parking attendant that we were gold pass members and that we were going to pick up our passes, she let us right in and said we didn't have to pay! We were also able to get front row parking at 4:00! There was not a line to pick up our passes and my husband forgot the credit card that he purchased the passes with, but they were super friendly and it wasn't a problem!
Once inside the park we were able to find a nice spot in the grass to lay out our towels and then we were off! All of the lines moved pretty quick overall. The longest line we waited in was the line for the Rattler, but it was well worth the wait! This was the best ride by far and it was fun because my whole family got to ride together!
Splash Island was great too because there are lots of little slides that my kids were able to ride by themselves, while my husband and I went on the Royal Flush. Now, before you think I am a crazy nut job of a mother, my kids are 9 and 7 and they stay together and they have a crap ton of life guards out there! Plus there aren't any actual pools on Splash Island so all my kids could do was go down the slides and squirt the water guns.
Despite a lot of people complaining about the park being too small, I felt that it was great for what it was. My family had a great time and we bought our season passes for our kids to enjoy themselves, which they totally did!! We will certainly be back many times this summer! My kids haven't stopped talking about today and they can't wait to go back!
