If I buy the combo for three attractions, do I have to go to all three activities on the same date, or I can do one each day/separate days?

I thinks you have up yo a year, we did them on the same day

Keep the barcode looking good. I think you have up to a year to use it.

You have up to a year to use them just make sure the barcode on the tickets does not get damaged.

No i bought them during spring break and only went to 1 & i just took my kids last week for the other 2. They last up to a year after purchase, as long as you keep the receipt.

I believe it is same day only! Unfortunately because they have to scan the ticket in and when sold they have the dates on them!
