I can't really decide, I just know that I won't have time to make icons today. One one hand I'm really bad at making icontest icons when there's not even suggestions (no matter that I can understand reasons for having one now and again) on the other I'm not even sure what to expect under Epcot (aside from the fact that it appears to be a disney theme park I've never heard of before, which most probably is easily explain by me having never been in America) so I guess either would be fine. Although, an extension would always give me the risk that I don't have time to search for sources and make icons. (unless someone sumbitted something already ;) )
