Went 1st time in WDW jan/2013 and only had 1 day to spent, Epcot was good choise! Place was easy to find and lots of things to do. As a tourist I found difficulties to locate all the things because lack of signs in the area. The worldshow was nicely implemented and for children it is educational like most of the other things around the area. All foodareas were crowded most of the time which made dining bit difficult even the two of us (no kids).
Still, recommend Epcot for families.
