When you call to have your luggage picked up, also call valet to pull your car around (if you are leaving immediately). They will have the trunk open and the bellman just goes over and puts the luggage in. You tip the bellman and the valet will come over with your keys (or you pick them up at the booth), tip him too. If you are not leaving immediatley, just tell the bellman to put the luggage into storage when he picks it up.
