I lived in Orlando, FL about 10 years ago and fell in love with Disney World while I was there. Disney World is a place were anyone can be a kid. Disney has always taken incredible care to make sure their parks look beautiful. As a result, there is plenty to photograph.
Besides the usual pictures of the castle, every ride built in the last 10 years has been built with extreme care. The details in everything from the walls to the walking paths show how over the top Disney is at making sure the theme of every ride shows itself the second you enter the line.
If you are planning on going down to Disney World, try and make it for the flower and garden festival at Epcot. Also, make sure you bring your macro lens. The butterfly tent is incredible!
