DS graduates from HS in early June of next year. He has worked very hard and there is a strong chance he could end up being valedictorian. DH and I are looking at the possibility of going to the World instead of having an open house after graduation (DS says he doesn't want one ). We are going to try to save where we can to keep costs in control a bit. So, we have 1 day hoppers on our KTTW from 2006 that are unused. I would like to "upgrade" these to help with the costs of the tickets a bit. I have no clue what we paid for them- can't find anything in the paperwork that I have. I thought there used to be a link here for historic ticket prices and can't find that either. Does it still exist? I know prices will be going up again (possibly twice) between now and then, but I would kinda like to get an idea of about how much they would cost without knowing what I paid for the original ones. Help! Thanks!
