As mentioned, no matter what time you turn over your luggage to Bell Services, nothing will start moving until 1pm. Disney does a massive, coordinated move from/to all resorts all art once (more or less).
Luggage being transferred is picked up at each resort and sent to a central facility where it is sorted, loaded back onto trucks and sent to the new resort. Pick-ups start at 1 and the prices can take 3 or more hours. Bags are "usually" at the new resort between 3 and 4, but it can be later.
Also as mentioned, your bags will not be delivered to your room automatically. You must call from your room and request they be delivered and you must be there to take delivery. Tips ARE expected at both ends.
