Because of train delays I had to find a hotel in the middle of the night. Crown Select was the third one that I contacted by phone, they asked me to bring 100 euros of cash as a deposit. I explained that I didn't carry that amount of cash with me and that I could pay the hotel bill in advance (by bank-card) but they insisted (policy of that hotel). With a taxi driver i had to find an available ATM / cash machine, which generated a much bigger taxi bill (many cash machines weren't available in Mönchen-Gladbach after 22 o'clock). In my opinion this policy is un-human, un-necessary (people leave their passport not for no reason!!!). un-inviting (especially when in an unpleasant situation at midnight as I was in). THIS SHOULD BE FORBIDDEN.
Pity for the hotel - anything else was good - one could skip the over-priced breakfast for 19 euros though.
