Thank you very much. I did some research and realized my original plan is impossible.

So I booked flights to Oslo and I will have one week in Norway. I am trying to minimize ferry and keep the daily driving distance below 350km (it might be still too long).

Day 1: Arriving in Oslo in the afternoon. Rent a car. Stay within 50km from Oslo airport
Day 2: Oslo airport - Sohlbergplassen viewpoint (NTR Rondane) or NTR Valdresflye. Stay near Otta
Day 3: Otta - E15 highway - Hotel Videseter - Stryneelva - Sogndalsfjøra Stay near Sogndalsfjøra (NTR Sognefjellet / Gamle Strynefjellsvegen / Geiranger – Trollstigen are closed)
Day 4: Sogndalsfjøra - Turtagrø - Stegastein Viewpoint - Flåm - Gudvangen - Vossevangen Stay near Vossevangen
Day 5: Vossevangen-Bergen Stay near Bergen
Day 6: Bergen-Eidfjord NTR Hardanger Stay near Eidfjord
Day 7: Eidfjord - Oslo NTR Hardangervidda Stay near Oslo
Day 8: Oslo Fly out

I cut Alesund and Atlanterhavsveien. There are a lot of things which I want to do (such as staying in an island). Any way hiking is out since one of members has a leg problem.

Do you think this revised schedule is still too tight? I am still worried about the road conditions in April, especially Day 3.
Any suggestions like skip a location or two would be greatly appreciated.
