Here's a tip from our own experience - take a note or photocopy the details on the back of your park tickets. If you lose your ticket, it'll be tough luck unless you can produce your issuer's time stamp and sequence number to disney guest services.
My wife had used all our tickets to get fastpasses for the family but unfortunately, as is easy done, mustn't have lifted one of the tickets as she was leaving the machine. We were able to get a replacement ticket because we had other tickets either side of the sequence numbers and the disney guest ppl were able to identify and null the lost ticket and issue a replacement. They told us though we were lucky on this occasion, so be warned - take a note of your ticket details.
