My daughter and I were in DLP over Christmas this year and had an absolutely amazing time, met loads of characters and really enjoyed our stay.
Unfortunately there was one downside to the holiday in that my little one lost one of her Christmas Elves on the way back from the park on Christmas Day night. We were on Autopia as the fireworks began and then walked straight to the park entrance once we were off and somewhere between the ride and Disney Village he got lost somehow.
I was absolutely gutted and she was distraught and I know it sounds silly but he was quite a big part of the holiday. All of the characters we met really interacted well with my little one when she had him. Marie was playing throw and catch with him between them both and Pinocchio and Gepetto put him up on the Christmas Tree etc etc so I'd do anything to get it back if possible although I know it is probably unrealistic to think that may happen with the amount of people that are in there every day.
It is worth a try however and I have attached a picture below of her holding the little fellow we're looking for...
