Question on difference in old and new tickets

[TeachGeekLove]

Hello! I'm planning a first time trip for my son and I discovered some old tickets. They were comp tickets from a trip in 2005 and won't expire for another few years. I can't tell you how thankful I am to have found these! It makes us that much closer to actually getting there!

Anyway, the tickets are UPH - Ultimate Park Hopper. I can't seem to find any info on that online now. Any idea what they'd be comparable to now? Thanks!
