This year we had a borrowed caravan car (Fiat globescout) from Askos parents. It was luxury compared to our vacation in 2016, when we slept in the car trunk. But with all the baby stuff etc. we were pretty squeezed on our 2 week trip ;) this year with the baby we couldn't drive that much a day and we were pretty much twice as slow as the previous year. Also instead of sleeping somewhere on the road, we went several times to camping areas. Pretty much every other night on the road and every other night on a camping area. The camping areas are pretty cheap in Norway. Something like 25€ which is even cheaper than the average camping area in Finland! So when people complain about Norway being expensive, it's certainly not everything.
If you have any questions about travelling to Lofoten, you can drop me a line :) I might know a thing or two ;)
