Hopefully someone can help me out here. I initially purchased tickets for Thursday and Friday (thought I was going to fly back in time for my 20th high school reunion Saturday night, then my sense of priorities set in). Anyway, I called the good folks at CV and they couldn't upgrade me to the four day pass because I had already received my passes for Thursday and Friday. I did the whole "would it be possible to speak to a supervisor" thing, but to no avail. The woman was very nice and suggested I try to upgrade when I arrive on Wednesday (I really don't want to pay for two more days when the upgrade would only be another $25 or so. Anyone else in the same boat or have some advice for me? Is it possible that Saturday could sell out?
