I have two split trips planned for the upcoming year. We have used bell services before but we have always dropped our bags off and then picked them up at the desk. I have read in other posts that BS will pick your bags up at your room and take them to your new hotel. My questions are: do you need to be in the room for them to pick the bags up or can you call and schedule pick up? How much should you tip? Do you tip the person who picks the bags up? Thanks
