I'll be visiting Copenhagen next month for 10 days. I've already got my visa, but I've got a question about my hotel reservation. A friend has kindly offered me a spare room to stay at (Amager Strand, conveniently close to the airport as well) so I am thinking about canceling my hotel booking.
From my previous experience, I know that the airport officials usually ask to see the hotel reservation. If I were to cancel the reservation, and tell them that I'll be staying with my friend instead, what kind of information would they require?
I tried searching online but didn't find a similar situation, except for some guy asking if he could produce the reservation copy for the canceled booking!
