Six Flags St. Louis on a summer Saturday
 

We are starting to plan our summer vacation. The schedule is working out that our day to be at Six Flags St. Louis will be on a Saturday in July. Is this crazy? Will it be so packed that it won't be enjoyable? Our kids are 13 and 10.

Been there...
 

My wife and I had went there in July. It does get slightly hectic. The lines for rides are a little longer than normal. But the crowds are manageable. Where the problem we ran in to is the eating. I suggest you eat at the car or stagger your meal times either earlier than normal lunch times. (When its the most crowded) But go eat earlier or wait a little while longer till the crowd dies down.
Hope this helps.
