Margly (Member # 18615) is from Norway.
I have been to Norway 1/2 dozen times and was actually married at the very top of Norway (top of Europe at 73 degrees N. Lat.) at Skorsvag.
It is the most beautiful country I have ever been to, I hope you feel the same after visiting. It IS very expensive, 1 dollar US = 8.33 Nor Krone but keep in mind a beer may cost 68-70 Krone or about $8 US. Culturally people are more to themselves and may seem reluctant to say "hello on the street" but are friendly and very interested in getting to know you on a personal level.
If you drink...bring the alcohol you are allowed per Norwegian Customs,
http://www.visitnorway.com/us/about-norway/travel-facts/before-you-go/customs-and-regulations/, as a gifts or other...it will be appreciated as it is very expensive and not readily available like here in the States.
It is not about drinking in Norway though...culturally they are not about indulgence; they are highly educated, healthy and mindful of the environment...a unique place indeed!
Enjoy your trip!

ps - you'll have about 20+ hours of sun then, you'll be jet lagged and that amount of light will mess with you too; you will likely not recover in that short time either.
