What is the local currency?
The currency in Norway is the Norwegian Krone (NOK).
Should I change money before I go?
Yes, though you will also be able to use your credit and debit cards in most places.
How much should I budget per day for extras?
We recommend about 1000 NOK extra per day.
Is it customary to tip?
It is not customary to leave a tip but if you find the food or service great then it is appreciated. How much to tip depends on the amount of the bill, generally 10% is a fair amount.
Then for your guide and driver, it is customary, though not compulsory to tip them around £8 - 10 a day, this would normally be given at the end of the adventure and is completely up to you and whether you feel they have earned it.
