Hello,
Last trip we split between ASMu and Poly. The day of the move we called down to bell services and they came and picked up our luggage from the room (you have to be there for this). Later in the day when we checked in at the Poly we went to the bell services and our luggage was there. They took it to our room. I had been worried before my trip about this but all went so smoothly that we are splitting our next trip as well.
