Copenhagen was excessively expensive when I was there on a business trip. Which lead to a huge hubbub when our secretary put me in an hour hotel unknowingly. When we had a presentation regarding travel directives and rules (along with HR) I asked what I should do in case I did not receive an invoice due to our secretary putting me into such an establishment, and if it was now company policy to force the female employees into prostitution just to cover the travel expenses.
Needless to say, no one was really amused.
There are also good hotels close to Istedgade where such activities are mostly concentrated. I'd regard the secretary as incompetent and worse, not aware of it.
These days, I vet all my hotel bookings for work trips personally, and mostly make them myself too. As noted in another post, we just came home from a 3-week vacation trip, with 17 different hotels. That's a personal record, that I'll try not to break again, for some time. We've managed to get good cheap hotels for the most part, with no disasters, which is a quite good record, frankly.
We usually break something during the trip. This time, it was a leaking tire. Got it fixed earlier today. Tire repair shops are usually pretty quick in condemning a tire, especially on AWD cars, but this one had a small leak in the track area, and that was patched quickly by a truck tire shop in southern Sweden.
I brought my tool case, and the socket set. And I did not open either. So no TE stories, except the pics from various generations of "stop-the-germans" buildings in France.
