Wanted something different for my 60th and a journey but with ease. This did it in spades.
Not a typical cruise as working boat but still good food, good lectures/info, fun expedition team to help and point everything out for you to ensure you see the most. Each cruise in different seasons will see something different. e.g. we couldn't go into the fjords because of avalanche risk so didn't see the beautiful scenery you get in them, but we were possibly the last to see the northern lights as it was getting too light as it changes into spring. You pay your money and makes the choice - or go again!
Cabin was on small side - we wanted double bed not twins but adequate. Upgraded to silver package to get coffee and tea making facilities and free wifi was worth it. but generally agreed not worth further upgrades to platinum
