1. Characters: Wondering what to do between fast passes? The Disneyland app has GPS on all the costumed characters in the parks. (If you have young children) find one and get in line. The character will take about 1 minute with each person/group, so count the people in the line. It's a good way to burn 20 minutes before the next ride. Our kids met about 30 characters (really). For posterity, here's the list: Mickey, Minnie, Goofy, Pluto, Mary Poppins & Bert, Darth Vader, Chewbacca, a Stormtrooper, Woody, Buzz, Flik (Bug's Life), Snow White, Ariel, Cinderella, Donald, Chip 'n Dale, Cruella, Fairy Godmother, Belle, Tiana, Rapunzel, Olaf, Daisy, Anna & Elsa, Fawn (fairy), Tinker Bell.
2. Fine print concerning characters: If you take the time to buy an autograph book, characters at Disney will sign it with very unique signatures. Ballpoint pen is awkward for someone wearing big Mickey gloves, so think more along the lines of a Sharpie. Star Wars, Cars and Zootopia characters do not sign autographs. Characters with masks and "mascot heads" do not talk, but will respond non-verbally to anything you say. The exception is the Star Wars characters. They have masks, but still talk. Except Chewbacca who growls.
3. One more thing about characters: Is it just weird to me? Or does waiting in line for a grown woman to stop fawning over a costumed Disney character seem a bit troubling? (This happened multiple times.)
4. The only rude person in Disneyland: We were impressed repeatedly by the level of service we received over the phone while planning, at the hotel during off times and in the parks during the main part of the day. Everyone was very patient and pleasant. This was with one exception. Cruella de Vil was completely condescending and pompous to everybody.
5. Most Seriously Underrepresented Franchise: The Incredibles. I saw about two Incredibles-themed items in a gift shop. That's it. Others who got ignored: Ratatouille, Aristocats, Uncle Scrooge.
