In reply to TobyA:
Yes, and it means many of those rental houses are filling up quickly leaving only the pricey ones.
I went last Easter, did Daltinden, Store Kjostinden, Kjelvagtinden, Russelvfjellet, Langdalstinden, Store Jægervasstindene and Fugledalsfjellet.
We didn't make it to all the summits as the conditions were difficult.
Planning to go again in May this year to try some of the couloirs.
Good to know the campervan approach can work, thought about getting a boat so we can ski from that instead
