I'm not certain in your case since you'll be at the same resort. If moving from another, I know you're not checked out. Even in your case, I would think your first set of KYYW cards would still be valid for charging or the
DDP until midnight even once your villa has turned over.
But as for vacating the first villa, my philosophy is always to get out as soon as it works for us in the spirit of "Do unto others" as I know how much we appreciate getting a villa before 4pm when possible. When we move, I often drive to the new resort and check in while my DH gets ready and moves our luggage down with our DS (I'm
always the first awake). I swing back to the first resort and we go about our day until the second villa is ready.
Another option is to call bell services in the first place if you know you want them to take care of your bags. They can call and check to see if your villa is ready.....or at least I know they have for me in the past. If it's ready, they'll
take you and your luggage straight up.
