We will be staying in Milan for just one night, at a average hotel by the train station. I am not sure if someone will take us to our room or what. If they do take us to our room, how much should the tip be? We will each have just one smallish suitcase with wheels, so it's not like we will need help with our bags. Also, assuming we don't order any room service, what other tipping situations should I know about? Thanks for any advice.
