Thank you for the wonderful trip report. I have travelled to Stokholm and Copenhagen on business several times but never seen much of the cities so it is great to see your pictures.
Your pictures of the Radisson Blu Strand in Stockholm reminded me of my stay there. I was in a very memorable room in the circular turret at one corner at the front. I checked in late in the evening and checked out again early in the morning - I maybe had the room for just 8 hours and I think it is possibly my most expensive hotel room per hour spent in the room - hotels in Stockholm aren't cheap. (I hope that doesn't sound too dodgy!)
