One would think that most hotels these days offer Wi-Fi Internet access to their residents. Or at least provide a free or low cost cable connection.
Unfortunately, this was not the case for the hotels where I spent my nights during the last few weeks.
Luckily, I got my hands on a UMTS prepaid surfstick. It's not as fast as my DSL at home, but I'm finally online again! It even works in the train between Stuttgart and my current working location. The connection there is not super stable but suitable for mailing and browsing the web.
