It’s time to “Jingle Bell Rock” on Episode 22 of Dateline Mousetalgia, as this week’s episode is all about the music that can be enjoyed during Disneyland Resort’s holiday celebrations! We’ll talk festive sounds in Disneyland, including “it’s a small world” Holiday, and we’ll take particular care looking at (and listening to!) the sounds celebrating several holidays as part of Disney California Adventure’s Festival of Holidays. It’s also a great time to discuss Mary Poppins in the parks, as the “Mary Poppins Returns” sequel will hit theaters this month! We talk where in Disneyland to find Mary Poppins and Bert, clever nods to our favorite magical nanny in the parks, and a new temporary special exhibit in the Main Street Opera House lobby. Plus– exciting news regarding the soon-to-open Tropical Hideaway in Adventureland, Marvel updates, new merchandise, and a look at some of the foods at Festival of Holidays in DCA.
