A few years ago I've visited a hotel in Munich and was pleasantly surprised to find there was no reception as such. To get the keys you had to call a 24/7 support line, where you received a code to a locked box outside the hotel door, which contained the key to your room. It wasn't required to show any IDs or fill out any forms. Upon checkout you simply placed the key back into the box, no questions asked.

I'm not a paranoid person nor am I hiding from the law, however I find the concept of traveling anonymously appealing. Is there a way to find out in advance if the hotel in question allows for fully anonymous check-in? And is there a website which allows you to find such lodging?
