I think it's about the same distance either way, but I have had good experience getting into the IG without much of a line at bag check/turnstiles. However, the front gates of Epcot often open about 15-20 minutes earlier than stated park opening. Sometimes, the IG entrance does not open at that time. Either way, I would have at least 1 adult go straight to Norway and get in line. Note: for now, I think they are back to meeting at 11 so you will have a minimum of a 2 hour wait, unless they change it back to 9 AM before your trip.
