I have tickets from 1999 that have not been used are they still good? no expiration date on them.

I think they are good for 1 calendar year. Call their support though to make sure

I would call there tickets are all scanned now I was just there last month but 20 year old tickets beat me

I agree with the friend's answer. Anyway try to get in touch directly with the park.

I was yesterday and the tickets is valid for one year only ...But tickets from 1999 year im not sure but maybe have some value because its old..if you never use...we never know my friend..

I'd think so, my friend just said he knows a lady that had tickets from a long time ago and they honoured them. And it's more in their interest for you to be in the park spending money, than outside complaining
