Hotels:

• We booked every hotel/apartment the same day online
• It never was a problem to find an accommodation
• Rooms are affordable, Petersberg offered 5 star luxury for 3 star cost
• Hotels might close already at 8 pm, call early
• Hotels and especially cabins might have no restaurant and the next place to eat could be an hour away, have some canned food and cookies with you

Roads and car:

• A lot of snow and ice
• Conditions can change within seconds and with pure ice just around the corner
• Spikes do make sense and are common (from Sweden to the Baltics)
• 4-wheel makes sense
• Small bluetooth speaker is great for music and audio books

Clothes:

• Be prepared for a wide range of temperature, you might have +15 C in Hamburg,
  0 C on the Lofoten Islands and -30 C somewhere in Finland
• A warm fur hat makes a lot of sense (especially with my hairstyle)
• Lined warm trousers are great
• We never needed our super warm gloves
• The super warm boots were needed only a few times, but good to have
• Our super warm jacket was great
• As long as you plan no extensive outdoor activity, you don’t need to much warm stuff, but keep in mind that your car might break down … for that reason we had as well polar sleeping bags
