EPCOT: I have to agree.. I saw it from between UK and France last Feb and it was a terrific view. If you are walking from UK to France, down on the Left is a little Patio. If there are no occasions, it is open and its a great place to sit and watch. Good Pre-Illuminations people watching too! Also heard Mexico is a good spot. Get some drinks and sit at some tables and wait.
MK: We watches Wishes from just outside Casey's. We'll probably do this again too. Great view, got to see it all, and even spoted Tink!
