This is the iconic Disneyland shot. Everyone wants their picture taken here. My advice is do not take the shot when you first enter. The lighting is terrible and it is so crowded there first thing. Wait until later in the day when the crowd has thinned and the sun is in a different spot.
Back in 1955 on opening day Walt Disney gave a speech to open the park. It is engraved on a gold plate at the main flagpole. It is worth stopping for a second to read it and soak in the history.
The flowers are so beautiful on Main street. They are perfectly planted and always look amazing.
In this area there are usually a character or two standing around posing for pictures. It is a great opportunity to get photos with your favorite characters. Mickey, and Minnie are often found here first thing in the morning. BUT if you don't catch them here, they do have their own houses in ToonTown and you can see them there.
