i've seen mention of people upgrading tickets, but i can't really find out what that means. i did a few searches to no avail, although i'm sure this has been discussed plenty of times
here's what's up...we are meeting my parents and brother's family in dl next week. we will be staying four days longer than they are, but already have the tickets for the first 6 days. so...i'm looking at buying 4 more 4-day hopper tickets. is it better to get an ap and hope we make it back within a year? how does the upgrading even work? any help or pointing to the correct thread is greatly appreciated!!!
