When is the most busy time at the park

Weekends and evenings definitely

Weekends get very busy! If possible you should go in the off season if you can. Usually as the kids finish summer break and go back to school. Otherwise the park gets busy most days, I have been there early in the morning and I had got a few rides in before 11am.

Weekends without a doubt.

Weekends and later in the afternoon, get there when they open.
