I have no shame in admitting that I love, love, love the opportunity to pose with my favorite Disney characters at the park. My absolute favorite is Goofy, but I also love Mickey, Donald, and the ladies, Minnie and Daisy.
Of course, I will let the kids get their pictures first...ahem, but I am not too shy to jump on in there and pose.
Tip: definitely invest in the Disney PhotoPass. Find a Disney Cast Member with a camera and ask them to take your photo. They will happily take several then scan your Magic Bands to load them onto your MyDisneyExperience.com account. When you get home, you'll be able to select, purchase, and download your favorite photos. I like to take my own, but they are especially great for group photos that you might want to be in.
