I have opening day tickets too! I think it was a three day pass, and because they left people staying at the park, they left us in the day before. So luckily we saw almost everything the day before. I remember Spaceship Earth was down most of opening day, so we were lucky to see it the day before. That was my first time at Disney, so everything was so magical.
I would like to see how much the tickets are worth. I have two adults and one child
I see if I can find the tickets and scan them.
