Hello there Dynasty,
Welcome to planDisney and thank you so much for your question! It looks like you're planning a trip for later this year during the
Halloween season, which is one of my most favorite times to visit!
Embroidery is such a great way to personalize your favorite ear hat! There are
many locations located around the Disneyland Resort that offer embroidery services - including the
Disneyland Hotel. Though I can confirm that the ear hat that you'd like to be embroidered must have been purchased at the Disneyland Resort during your visit.
When requesting the service, you'll be required to show a proof of purchase for the item, so if you decide to purchase a new ear hat during your upcoming visit then make sure to hang on to the receipt or purchase email.
Since you'll be visiting during the spooky season later this year, keep an eye on the
Disney Parks Blog as you get closer to your trip for the inside scoop on what will be happening during your visit! In particular, I love the Foodie Guides that outline all the delicious seasonal food and drinks on offer.
Thanks again for your question, Dynasty! Enjoy your trip to the Happiest Place on Earth.
Have a Magical Day,
Greg
