Welcome, Laura!
Thanks for bringing your question to the Disney Parks Moms Panel. A trip to the Happiest Place on Earth isn't complete without some fantastic souvenirs. I think a custom caricature done by a talented Disney artist is a perfect keepsake to remember your magical vacation. Last I checked, these artists were located in New Orleans Square of
Disneyland Park and near World of Disney in the
Downtown Disney District close to where the parking trams load.
Another unique keepsake option is to get a hand-cut silhouette on Main Street, U.S.A. in Disneyland Park at the
Silhouette Studio. It's amazing what these artists can do with a tiny pair of scissors in such a short amount of time. They can perfectly match your silhouette free-hand! I sometimes just stop to watch them work, because it's so impressive. I also love that these are pretty inexpensive and also come with the option of a custom Disneyland frame. I can't wait to collect more of these silhouettes of my son over the years to see him grow up.
I hope this helps, and I can't wait for you to collect some wonderful memories of your vacation!
