I didnt know that 3 and younger get in free. Would I get a refund for purchasing a season's pass for my three year old?

I don't know, but you should call and ask them.

Yes

They Should I don't see why not.

Yes,but ask the people there.

I would not purchase the pass for your 3 year old. They are free.

Yes u should but they shouldn't have to pay for that in the first place

Talk to the manager or staff because you should get that difference back
