Hi. Do you mean that you obtained one day tickets through Airmiles and were then able to upgrade to a 2 day ticket at the park if you wanted? This is our first time going to US. I think we will only want one day there, but wanted the option to upgrade to a 2 day before leaving the park if we felt like it. I was concerned I would not be able to do that if I got my tickets through airmiles rather than the park. Also, I was wondering if you receive an actual ticket so you can go on through the gates or do you have to line up at the front entrance ticket windows with a certificate to gain admission? I would love to use my airmiles but not if I need to stand at the front ticket window for an hour with those waiting to buy tickets before I can get in the park and then cannot add another day if we want.
