We're planning to do our first split stay in late April, 3 nights at Poly, 4 nights at AKV. I'll be alone with my kids for the first 3 nights, then DH is joining us for the last day.

I actually have a logistics question, though...
I was planning to pack up early on switch day, and leave my bags with the bellman and head off to AK with my kids. I thought I'd read on the Dis that bell services will transfer your luggage for you. So, then, I'd be at AK with my kids all morning until early afternoon, and then just go directly to the new hotel (AKV) and check in.
Will this actually work? Or would I have to backtrack to the original hotel and get my bags myself, then schlepp them to AKV?? That seems like a very bad scenario.... anyone know the answer about whether Disney will transfer my bags for me?
