Question about a split stay

[Twingle]

We have a trip upcoming in October at SSR, and are waitlisted for one night right in the middle of our stay.

We can stay at Shades of Green that one night, but my question is:

Will Bell Services hold our luggage for the one night, and we can just take an overnight bag? Or, do we have to transfer all of our luggage, and then transfer it back?

And, if we have to transfer it, will Disney take it to Shades of Green? Will Shades of Green transfer it back to SSR?

Thanks for any help you can give me!
