Yup, Bell services will transfer your bags. When you check into YC, let them know you will be moving resorts, they will put it in their notes.
The morning you are checking out, call Bell services, tell them you are moving resorts, the bell services guy/girl that picks up your bags will put them in a transfer area, instead of a storage area.
They will transfer them, but like it was said earlier, it could take a few hours.
When you check into SSR, let them know you have moved, and area waiting for bags.
They make it pretty easy.
Have a great time!
