In Europe, my bike has never slept outside. It always goes to the room or to a secure storage area provided by the lodging host. In Cologne, the owner had us lock our bikes to the table where we would be having breakfast the next morning. It was his suggestion. In Lyon, the manager of the Formule One suggested we put them in his office where he could watch over them. In Burgos, the owner had us take them to the second floor and lock them up in the TV break room. In Frankfurt (Hochst), the berths were too small, so the bikes went into the cloak room by the bar. The attitude is this - your person has a higher probability of sleeping outdoors on a park bench than your bicycle sitting outside. If you have panniers on your bike, it is the same as a suitcase on wheels, only the wheels are bigger.

And believe it or not, in the United States, Rozinante (my bike), has never slept outside either. Management has always encouraged the bike in the room and if there is an issue, they provide an alternate manger for the steed. Roll on.
