Norway route

[Wagonwheal]

Hi All, we arriving in Amsterdam Saturday morning for a 2 week trip to Norway and have not really made any plans yet!
We have a Ferry out of Kristiansand for the way back so we are aiming to drive to Lillehammer in 2 days with overnight stay in Copenhagen to take the big bridge in the morning.
Has anyone driven this in 2 days? Am I being overly optimistic?
We are 4 in the van but do drive to Cornwall from Edinburgh each year in a day with no bother. The California is so much more comfortable than our previous family cars!
