We leave for Disney on Thursday. We already have tickets that my parents gave us that we used years ago that still have days on them. My parents purchased them from someone who only used 2 of the 7 days in 2003. We used 3 of the days in 2007. The tickets all have our finger scan on them. Will we have a problem switching the tickets over since we were not the original buyers? My sister has sent the tickets to Disney to check the days remaining and they never said anything about her not being the original buyer. Has anyone ever switched old tickets to the new system when you weren't the original buyers?
