Spread it!
Although the ferry to the Magic Kingdom takes a bit longer than the Monorail, it provides lots of beautiful views of the Seven Seas Lagoon, the Polynesian, Grand Floridian, and Contemporary Resorts, as well as many other boats traveling the waters of Disney World.
The ferry boat often provides a welcome solace from the hectic atmosphere of a Disney World vacation. You just sit or stand, taking in the scenery and outdoor air while the boat carries you to your destination. You can see what the ride is like in the video, below.
