I usually tip the person a BS who takes my bags from the car and then tip the person who brings them up to the room since they are not the same person. I tip a dollar a bag unless I only have one bag then I usually had them between 3 and 5. The only time I haven't tipped BS is when I was saying at Swan, instead of leaving them in the car, which I normally would have done, when I checked in I brought them in with me since I was expecting my room to be ready. It was not so we handed them off to BS at the BS stand. We had brought them from the parking lot into the hotel ourselves and took them over to the bell desk. When we finally got our room later in the day, again they were just brought up to the BS desk and we took them to our rooms so we didn't tip.
