I'm assuming that you will be taking the monorail to Epot from TTC. I would try to be at Epcot for opening at 9:00. So get the monorail around 8:30ish. Then you have to hike back to WS to get to Norway. That will take you about 20 minutes or so. If you are there for park opening you won't have to be in a huge rush. You can just take your time. That's what we plan to do.
