If renting from an owner, ask the owner to give Member Services the Disney confirmation number for the RCI exchange and ask that a “continuing stay” notation be placed on both reservations. If the extended stay is booked directly through Disney, the Disney reservations CM can do the same. That lets the room assigners know to keep them in the same room, if at all possible (assuming same villa size, resort and view).
Maybe not for a 1BR that is covered under the summer discount. 1BR are by far the least efficient stays on points. It might be a little bit cheaper through an owner but it is a LOT easier through Disney.
I agree - check the cash availability and cost from Disney as well as via renting from an owner. Disney’s payment and cancellation policies are much more flexible than owner rentals. Also, availability can be different between owners and cash.
Pretty sure Disney will still move luggage between resorts if they want to or have to move. Just tip on pickup and delivery.
Yes, Disney still moves luggage. Just call Bell Services for pickup or bring them down yourself and head out to the parks. The luggage will arrive at the new resort in the late afternoon, so it’s best to keep anything you’ll need during the day with you. Then head to the new resort and go by/call BS when you have your room.
PS if changing resorts, be sure to completely check out of the first one when leaving it, otherwise there can be problems with getting into the new room. And you can use the pools, parking lots, and other facilities of both resorts all that day.
