We are currently on the MS Richard With on the 12 day Bergen - Kirkenes - Bergen trip.
Overall very happy with the whole trip. Staff are friendly and the ship is warm, clean and comfortable.
To sum up
Cabin - we are in 370 star board side. It's a triple room but there are only 2 of us. It doesn't give us any more floor space but we do have towels and bedding for 3 people so plenty of spare pillows etc. Deck 3 cabins don't have tea/ coffee making facilities but they do have a dressing table/desk area with a plug and we've brought our own kettle and stuff so are quite happy. The cabins we've nosed in on Deck 5 are exactly the same as ours - with a kettle. I'm glad we didn't go for a deck 5 cabin, however, as it is a wraparound promenade deck so people are walking past or standing in front of your window all day (and night if the Northern Lights make an appearance). We have a window and it's been perfect some nights e.g. in Tromso we had a lovely moonlight view of the Arctic Cathedral from our cabin. The toiletries in the cabin are in a wall dispenser. Hand wash over the sink and combined shampoo/body wash and a separate conditioner in the shower. I really like the toiletries but I suppose it's personal preference. For this time of year I would recommend you bring some decent, intensive hand cream, lip balm and moisturiser as it is warm on the ship and the air is very dry. Plus you're going in and out all day in the freezing cold. It's useful to have slip on shoes - I've seen a few people in crocs- for getting around inside the ship, as long as you're not planning on going outside in which case you need your proper shoes. As others have said - a lanyard is useful for your room key, but you can also just keep it handy in your purse/wallet.
