yeah we've looked into the lyngen lodge and will probably ski some of that area. but the actual lodge was too expensive for us 5,000 USD per person for a week and it would be guided - we weren't looking for guided. looks awesome though - if it was cheaper!
I see that you have already booked a RV, but you can also try to contact this place. I know the guy that runs it from a mtb forum I frequent. Seems like a nice guy and a budget friendly place! http://www.campkviteberg.no/info.html
