Yup! That's what we were told, too! Wedding events only -- our trip around the countries after Illuminations wasn't a problem because 1)the CMs left at Epcot probably had no idea we weren't supposed to be doing what we were doing and 2) the park was almost desserted because it closes after Illuminations so no one cared that we were there.
BUT we were dying to take everyone over to MGM to do Tower of Terror -- we had several CMs with silver passes, so we didn't need tickets into the park and we BEGGED them to back door us (though we were more than willing to stand in line). No, no, no, was all we heard everytime we asked (and we started asking when we booked the wedding). Oh well!
That picture at the wedding pavilion is BEAUTIFUL! I only have one from our wedding on my PC:
