Ticket confusion--no expiration add-on?

[Meteora]

So I am, for the first time, looking into purchasing tickets to US. We were planning on one day, one park passes, since our priority is WWoHP. However, I was wondering if it would be a better deal to get more than one day and use the other day on future trips. Is there a no-expiration option, like at Disney?

Universal's tickets expire 14 days after the first used day. They do not offer no expiration as far as I know.

Thank you!

Back quite a few years ago, we purchased 3 day tickets with no expiration. We still have 1 days use left.
