Oh, one more question! Can the swan or dolphin transfer luggage to another resort. We are doing a split stay and would need to go from the Swan/dolphin to the Poly.
Having done it many times, I recommend dropping your bags at the Swan/Dolphin bell stand in the morning - on your way out to the parks, if that's on your schedule that day. The Swan and Dolphin transfer bags to Disney resorts via Town Cars, so the bags don't sit there very long, before they are on their way. I believe that the same cannot be said for the opposite direction, though, where Disney resorts accumulate the luggage to be transferred.
When you arrive at the Poly, you can either collect the luggage yourself at the bell stand, or call to have it delivered, once you are in your room.
I had a minor scare, the last time I transferred from the Swan. When I arrived at my Disney resort, later that day, I stopped at the bell stand to collect all of my belongings - and I do mean all!
A CM checked, but told me she couldn't find my transfer. I was told to check back later in the day. After checking two more times, and being told there was nothing for me, I called over to the Swan. They said they could not tell me when my bags were picked up by the car service, but would check into it. I called back, again, and the Guest Services rep apologized for not having any further info. I was in a panic, as the bell stand does not give out receipts for bag transfers. When I called the last time, I was standing at the bell stand of my Disney resort, and a CM overheard my conversation. He approached me, asking for all of my info - name, number of bags, etc.; he proceeded to go behind the counter where another CM had repeatedly told me they did not have my belongings. As he looked through the notebook, where they keep a list of received transfers, he started reading off my delivery. It had been received hours, earlier, but whoever entered the delivery noted it as coming from the Dolphin, not the Swan. The CM who repeatedly told me my bags were never received apparently only checked by resort name; she never bothered to look for my name.
As the second CM told me that he would bring out my belongings, the original CM avoided looking at me. She never even apologized. Needless to say, the second CM received a very nice tip for his efforts. And, after getting angry with the Swan rep, when thinking my belongings were lost or stolen, I called back and offered profuse apologies. I also sent a message to her manager, recognizing her patience and great service, when the Swan did nothing wrong.
