Our family went on Tuesday, June 30. Only the north gate was open. The crowds were almost non existent. We did a walk on to just about every ride. The longest we waited was for Cobra, for which we waited about 15 minutes.
As others have stated, food is very expensive. For example, one counter service restaurant had four small to average size chicken fingers and fries for over $8. All meals were about the same price. You can buy a refillable drink cup for $7.99, but refills cost $2.99. Or a small drink, maybe 20 oz, for $3.49. Large drink, maybe 32 oz, for $3.99. You can get water for free, but they give it to you in a 6 or 8 oz cup with too much ice. Many folks do go off site for lunch (or a picnic at their car), then come back to the park. They do inspect all bags as you enter, making sure you are not bringing in any food or drink.
All employees were very friendly, and they were very visual about safety. Before a ride would leave the station, all had to give a thumbs up, and press the button saying it was good. A number of employees asked how we were doing while we were walking in the park.
They have alot of carnival style booths which cost extra. Just walk by. Don't make eye contact. That overstuffed animal is really not worth the $50 you spend to 'earn' it.
I had not realized that they had changed owners, but I thought things were nicer than the last time we was there a couple of years ago. Some rides had new names. Top Gun is now Afterburn. Borg is Nighthawk. I couldn't figure out why they changed the names, but having a new owner makes sense.
They do have a kiddie section. As someone else mentioned, if the kids are tall enough to ride some of the rides, get the wrist band. It saves alot of hassle. The Park Map is also very good about listing the height restrictions.
It is a nice day park. Just be prepared for the food cost. Check out their website for adminssion deals. They did have a one day pass for four people for a total of $99.
Just made me feel like I was 8 yo again.
