Our DD was 2 when we went in May - we were on the regular plan, ate breakfasts in the room (except one) and had CS lunches. We also had our 4 year old son. I'd say their fave restaurants were Crystal Palace and Chef Mickey's. They loved seeing the characters -Pooh Bear and friends was a huge hit for DD. The buffets are nice b/c the 2 y.o. can eat whatever they want! We did CM for brunch, which worked out very well, and was a bit of a change. We'll be trying it for dinner next time. We also ate at LeCellier and Kona - no characters, but great food for everyone, and the kids did fine there. Our other choices were Wolfgang Puck (very good) and Whispering Canyon (not so good). Kids were fine in all the restaurants.
I think any of the character meals would be great for your little one!
