I have 4 tickets, Admit One Guest for Universal Orlando. They are old from 2000, and do not have an expiration date on them. They have numbers on the back of each ticket. Would they still be good?

I would call and confirm. Usually they are valid for 6 months or so from date of purchase

The operators have tkt valid now, that is, they have expiration. I recommend you speak by phone to gest relation.

You should call and confirm before you try
