Hey there, Marco!
Welcome back to the Disney Parks Moms Panel and thanks for your great question. A friends trip to the Happiest Place on Earth sounds practically perfect in every way!
I love customized gifts and souvenirs at the
Disneyland Resort, and I think matching personalized phone cases would be such a fun way for you to remember your epic vacation. Last I checked, you could customize phone cases including ones for iPhone XR at the D-Tech on Demand stations inside Disneyland Park. These are located inside
Star Wars Launch Bay. You can choose from a variety of options inspired by the Parks, Characters, or your favorite Disney or Star Wars films. Many of them even let you add your name for even more of a personal touch.
These D-Tech On Demand stations also JUST released some fabulous magnet options which you can also customize. They are fairly large and would be great for your fridge or car. Some offer cute designs with "My other ride is a Monorail/Doom Buggy/Fun Wheel, etc..." while others show iconic locations in the parks or adorable Characters. I can't wait to check these out on my next trip!
I hope this helps, and please return if you have any other questions. Have a magical trip!
