The number one thing I would do is spend the whole time with Anna and Elsa. Like they would walk through the park with me and ride rides with me and eat with me.
Personally, I'd sleep at the Polynesian and/or Port Orleans Riverside. But if I had to pick a place inside the park, I'd pick either the Cinderella Suite, Big Thunder Mountain, or a shop in Norway ( because I love how it smells). I'd take pictures of everything and eat at nearly ever restaurant. The top few rides I would do first would be: Toy Story Mania, Winnie the Pooh, Big Thunder Mountain, Test Track, Kilimanjaro Safari (like a trillion times), Kali River Rapids, and Rock n Roller Coaster. Honestly, I think I'd have a blast on my own.
