Hi there, Paula, and welcome to planDisney!
Thanks for submitting your question to us and I'm excited to see that your trip is almost here! I absolutely love your idea to have a photo mat signed by all the characters that you're going to meet on your trip! That will make one super special memento of your trip and it would definitely be something that you could use to look back fondly on your vacation.
Unfortunately, neither Disneyland Resort nor Walt Disney World Resort has a location that you could leave a photo mat for characters to sign. But that doesn't mean that you couldn't physically bring a photo mat to them and have each one sign a spot on it! You'll have to strategically plan each Meet & Greet but it would be a fun quest to go around and get the signatures you really want. You can see which Characters are going to be featured by using the pull-down menu on the Map screen of the
Disneyland Mobile App (or
My Disney Experience) and selecting "Characters."
A few tips I might have would be to bring only the cardboard mat and not the whole frame. The
Park Rules prohibit glass containers, so I wouldn't take the chance that a glass frame might not be allowed through security. Take precautions to adequately protect your photo mat as well (I've heard others who sandwich it in between other pieces of cardboard and carry it in one of those large Disney bags). Bring Sharpie pens (that don't bleed) in a variety of colors to jazz up the frame. And don't forget to grab that all important picture that'll go in the center! I'm sure that
Disney PhotoPass photographers would love to help there!
Paula, good luck on your autograph side quest and I wish you a truly magical visit to the Disneyland Resort! Please feel free to write to us again if you have more questions. We'd love to hear from you and you're always welcome at planDisney!
Wishing You a Great, Big, Beautiful Tomorrow!
