My DD has been at 2 yrs 10 months (last Dec) and 3 (this May), and other than MK, her absolute favorite park is Epcot. In fact, I asked her last night if we went back to WDW where did she want to go, and she yelled EPCOT. On her 1st trip we were there from open to close and did not feel like we had enough time. She loved World Showcase and we spent most of our time there. Epcot is about letting the kids take time and explore instead of running from attraction to attraction. There are lots of princesses in WS to meet and the lines aren't too long. She loved the street performers and kidcot stationsn(watch out the markers are sharpies and they will stain). She could spend hours banging on the drums at the outpost. She likes just exploring the countries. She runs around Morocco pretending it is Aladdin and Jasmine's marketplace (in the afternoon you will find Jasmine near there sometimes with Aladdin or Genie and that is what got her started) She likes the toy store in the UK and you can usually find Pooh and Tiger or maybe Mary Poppins or Alice there. You can also find Auroa, Belle sometimes with Beast, Snow White sometimes with Dopey, and Mulan. We did not do much of the Holidays Around the World because all the different Santas were kind of confusing for her. We also did not do the Candlelight Processional. I watched some of it on You Tube and although she really likes shows decided that was not one she would sit through. At 3, she did like the film in China. She was impressed that the movie was all around you. She loved the boat ride in Mexico and wanted to ride it over and over on both trips. On the Future World Side, she loved the Nemo Ride, exploring the area at the end of the ride and at 3 loved Turtle Talk with Crush. She loved the Journey into imagination ride and the area after it. Unless your child is absolutely huge, an "almost 3" won't be tall enough to ride soaring. If you get fastpasses, one of you could take your older daughter as I bet she would like it. The Character Spot area in FW was a hit (in answer to your question it is one area inside a building with Mickey, Minnie, Pluto, Donald and Goofy). Also, first thing in the morning there are usually characters out near the gate. We saw Stitch standing by himself just waiting for kids to come over. He spent a long time playing with DD until some other kids finally started heading his way. There is also a water splashpad area by Mission Space she loved in May, but it may be too cold for that in December, you just never know what the weather is going to be. If you let them play in that, expect them to be absolutely soaked. Forgot Illuminations- the fireworks show at night if your kids will stay up that late. She begged to stay for it at 2 years 10 months and then about halfway through said okay I'm ready to go to bed now we can go. At 3, she stayed for the whole thing. She likes it from a distance. She doesn't like to be right up by the water.
