Do unused days on tickets expire?

[Candace]

I have three 3-day, 2-park tickets from 1998. Only 1 day has been used on two of them, the other is still new. Are these tickets like Disney's parkhoppers? Please tell me they are still good! Thanks

Unused days on those tickets never expire.

Thank you, Barry!
