Stay on the Monorail
There are three Disney resorts located on the monorail system, ranging from the most affordable (Disney's Contemporary Resort) to the least (Disney's Grand Floridian Resort). We opted for the midrange, Disney's Polynesian Village Resort.
I'm not going to lie to you and say it was cheap. There was a lot of saving involved in making this stay happen. But for us, being on the monorail was a lifesaver. It allowed us to come and go from two of the four parks with ease, making space in our day for naps and a chance to get out of the sun.
Giving my daughter those easy outs proved crucial to her being able to go back and enjoy the parks later in the day.
