DisneyWorld in Feb. with a 1yo and 3yo

[Corrinne]

We'll be going to disney in february and my son will be 15 months and my nephew will be 3. I remember when my brother and sister were little going to a disney junior show and I know it's a small world is a must do as that's been my favorite since I was tiny also. I was just wondering if there are any other must do's besides like pirates, dumbo, slow moving rides, etc. Or any other general advice for small kids. Also my husband NEEDS to do anything star wars lol so I was wondering what's new. I haven't been since 2013 I know there are lots more star wars things added since then.
