Most of the cabins can be found on Decks 4, 6, 7 and 8, and all are clean, snug and functional rather than stylish. Although standard cabins are rather small, the limited space is largely a nonissue as most passengers are purely in their cabins to sleep. However, all have a desk and chair/seating area, and the beds, mattresses and bedding are good quality. Plus, Arctic Pure toiletries in all bathrooms are lovely -- the Cloudberry & Birch and Sea Buckthorn & Birch soap, shampoo and conditioners (in large dispensers) make you feel at one with nature and have revitalising properties after a day of exploration. Deck 8's suites boast bathtubs, but all other cabins are shower-only, with a hair dryer and a heated floor operated by a switch.
There are 297 cabins in four main categories: Expedition Suites, Arctic Superior, Polar Outside and Polar Inside. The majority of staterooms are 107 square feet and decor is Scandinavian-efficient, with light woods, white walls and navy-and-red accents. Be sure to pack an eye mask if you've booked an outside cabin because there are no blackout blinds and both the Arctic and Antarctic light seeps in.
Storage space is adequate, though cupboards could be deeper. There's a 115/230-shaver outlet -- otherwise it's all 230-voltage and requires a European adaptor.
All cabins have TVs and maid service (once in the morning), but cabins from Arctic Superior upward are offered a nightly turn-down service too and also have kettles, which is a nice touch. Expedition suites have mini-bars and safes -- other passengers wanting to keep their valuables under lock and key will need to store them at reception. Whatever cabin you're in, there is no room service available.
MS Midnatsol has 16 interconnecting cabins and suites and four cabins that are accessible for wheelchair users.
Interior: The majority of Polar Inside interior cabins are equally distributed across Decks 4, 6 and 7. Most cabins accommodate two people -- a few have double beds, but the majority have one single bed and one convertible sofa. There is one interior cabin which has four single beds (made up of two bunk beds) which makes a great economical choice for a family.
Ocean View: Outside cabins fall within the Polar Outside and Arctic Superior categories, and are marginally larger than interior ones. Those at the front of Deck 4 have portholes, but the rest have windows. Be warned that some cabins on Decks 6 and 7 have limited or blocked views due to being situated behind life boats, so if you don't want a blocked view, you must choose a specific cabin before sailing.
Several Polar Outside cabins sleep three people (more than 20 on Deck 6 and 14 on Deck 7), and there's a good range of interconnecting cabins which are particularly good for families. Four wheelchair-accessible cabins can be found on Deck 6 -- all sleep three people and have extra wide doors and larger bathrooms, as well as alarm systems.
Outside cabins on Deck 6 all overlook the Promenade Deck, so if you're uneasy about passengers being able to peek in through your window, perhaps select a different deck. In truth, it's very hard to see into these cabins (it requires a lot of voyeuristic intent), and the solution is probably to just close your curtains if you're in that cabin and not worry about it.
Balcony: Five upper deck Expedition Suites at the back of Decks 7 and 8 boast private balconies which have outside seating areas with enough space for two or three people.
Suite: All Expedition Suites are on Decks 6–8 and have double beds, tea/coffee-making facilities and mini-bars. No milk is provided (it's a cultural thing -- Norwegians don't tend to add milk to hot drinks), but you can get some from the Bistro on Deck 5 or from the bar on Deck 8.
The mini-suites and suites are, by far, the most superior and spacious accommodation available, and all these cruisers are entitled to a daily VIP waiter-served breakfast in Midnatsol's a la carte restaurant as well as complimentary drinks with dinner, a bottle of Champagne at check-in and free Wi-Fi and movie packages. Owner's suites have a small lounge area adjacent to the bedroom and Deck 8's suites have bathtubs as well as a shower. Light is excellent (thanks to large windows with unobstructed views) and suite passengers receive small souvenirs which can be taken home.
Good options for families include two grand suites which interconnect with an Arctic Superior cabin as well as one owner suite which interconnects with a Grand Suite.
Grand Suites boast either bay windows or balconies, with curtains to separate the sleeping area from the lounge. Owner's Suites have balconies and lounges which are separate from the bedrooms.
