Buses are running between resorts and parks by 6:30am every morning. I wish that info that they start an hour prior to park opening would go away. Anyway.....
These early morning buses do not run quite as frequently as the regular park buses do, so plan accordingly. To get to an 8:30am Akershus ADR, I would be out at the bus stop by 7:15, maybe even 7am. If you just miss a bus, you may have to wait 20+ mins for the next one. You will want to be at Epcot by 8am.
Then, once you get to Epcot, you will be able to enter via a turnstile that is manned by a CM with ADRs on a list. Your name will be checked off, and in you go. It should take you about 15 mins to walk to Norway, but at least you won't have to deal with crowds.
Hope that helps.
