You can call Bell Services to pick up your bags from your room (I’ve even called the day before and scheduled a pick up time on a GF/YC split) and you can call Bell Services to deliver your bags at your second resort once you are in your room. But you must be in your room both times, unlike DME where they deliver your bags from MCO to your room even if you aren’t in it.
I travel light, so I tend to just wheel my suitcase & carry on down to Bell Services myself & then stop by to collect them at my second resort on my way to my room.
