As you can imagine, meeting every character definitely takes some time to achieve — you won't find everyone in two hours.I arrived at the park shortly after rope drop (when it opens) at 9:30 a.m. and went straight to Snow White, who happened to be in front of the Town Square Theater. I waited for approximately 12 minutes to see her, had a cute interaction, and then made my way to Fantasyland. In Fantasyland, you can usually find a bunch of characters out in the morning.You'll want to visit Fairytale Hall to knock four princesses off the list — Cinderella, Elena, Rapunzel, and Tiana. Both pairs meet in duos on each side of the hall and the wait in the morning is usually less than 10 minutes. After I met the princesses, I saw Anastasia and Drizella who were to the right of the castle by Bibbidi Bobbidi Boutique. I waited 15 minutes to see them, took a few pictures, and continued on my journey.When the parks open, a lot of people are going straight to rides like Seven Dwarfs Mine Train or Peter Pan's Flight, so it's the perfect time to meet characters. I headed to Pete's Silly Sideshow (still in Fantasyland) where Minnie and Daisy were on one side and Donald Duck and Goofy were on the other. These lines tend to be a bit longer than some of the others at the park but aren't too bad. I waited about 20 minutes for Minnie and Daisy and less than 10 for Donald and Goofy.It was just my luck that as soon as I left that area, Chip and Dale were meeting guests so I quickly hopped on line and saw them. They had less than a five-minute wait which was perfect. On the way out of the circus area, Pooh and Tigger are usually right next to their attraction, The Many Adventures of Winnie the Pooh. However, the line for them tends to be painstakingly long, so I decided to skip over it and come back during a time I know would be less crowded. I walked around the corner and saw Merida in her little nook. She usually has a pretty long wait too, I'd say over 30 minutes on a good day, but I only had to wait 15. Characters like Peter Pan, Anastasia, and Drizella still meet while parades are happening. I caught Anastasia and Drizella towards the tail end of their meet and greet and waited less than 10 minutes to see them. Then I headed over to Peter Pan before he went to go check on the Lost Boys for a little bit. Peter's line was only 15 minutes which is great considering how popular he is.Some characters are out on a rolling basis throughout the day, but others come out less often so you'll want to make sure to get a spot on the line before they are scheduled to arrive. I'd suggest waiting at least 20 minutes before characters are set to arrive when it comes to Aladdin and Jasmine and Pooh and Tigger. Their lines tend to form and get cut off quickly. I waited roughly 40 minutes for Aladdin and Jasmine and 30 minutes for Pooh. There are a few characters in the parks who don't have lines — they just stand and interact with guests from a distance. Some of these characters include Stitch, Buzz Lightyear, and The Country Bears. You can usually find them in Frontierland and Tomorrowland. You'll be able to meet them each in less than five minutes as they make their way across the platforms pretty quickly.Anastasia, Drizella, Peter Pan, and Jack Sparrow are all characters you'll sometimes see roaming around their designated areas at random times throughout the day.You may not get a formal photo or receive an autograph, but these are a great way to see and interact with characters without waiting in lines. I'd never met Jack Sparrow in the parks before, but I saw him formally meeting guests on this day. I waited about 20 minutes to get a photo with him. People usually leave Magic Kingdom after the second showing of Festival of Fantasy around 3 p.m. so this is a great time to head over to Pooh and Tigger's meet-and-greet location, the Thotful Spot.The line to see them is always pretty long, but if you go at a less busy time of the day, you may get lucky and only have to wait 30 minutes.Mickey Mouse meets at Town Square Theater from the park's opening to just before closing. So, I'd prioritize meeting the characters who don't stay out all day first and save him for the very end. You may think that Mickey's line is super long because he's so popular, but that's often not the case. The wait time to see Mickey varies greatly throughout the day but it's usually about a 10- to 20-minute wait in the morning and near park close.To make the meet-and-greet experience as seamless and speedy as possible, have everything you need (cameras, autograph books) ready before you get up to the character. The attendants will tell you this as you stand in line, but it can get overwhelming and exciting so you may forget. Many characters don't have PhotoPass photographers who will take expert photos for you anymore, so keep in mind you'll likely be in charge of snapping your own. If you're alone, you can ask an attendant or someone else in line to take a picture for you. It took me roughly eight hours to meet every character at Magic Kingdom. I stopped for 20 minutes to watch the parade, but other than that I spent all day standing in line to meet someone. I probably wouldn't do this again any time soon but I had fun and I'd highly recommend it if you're also a fan of characters.
