I understand that bell services will deliver my checked luggage directly to my room once delivered from DME. If I am in the room at that time, do I tip Bell Services? Also on my day of departure, when I drop my bags at Bell Services to be held until my DME departure (I am flying SWA and cannot do RAC), it isn't necessary to tip anything then, is it? I would just tip when I go to retrieve my bags prior to DME bus pick-up? As far as tipping the DME driver, I expect to do that both ways. I have never used DME or Bell Services on any of my many prior WDW trips, so questions keep popping in my head.
