I just wanted to update everyone on this. We checked in to BWV on Monday at about noon. We got a great room, right above the store overlooking the BW. We promptly went to Epcot, and when we arrived back at 8:00pm or so, our bags were there from DME. We also called for our groceries to be brought up. No issues at all.
We left Wednesday morning for a day in HS. Had bell services come get our bags and groceries to be transferred to AKV. We arrived at AKV at around 7:30pm, checked in and had everything brought up to our room. We were out exploring by 8:00pm. Very easy transfer!
On Friday morning, we had bell services come get everything for our transfer back to BWV. Again, very seamless here. The only snag was when we checked into BWV and our reservation was a bit messed up. After fussing about this with check-in for about an hour, and then having to wait an hour for our room to be ready, we were off to Epcot for the night. We did swim at BWV and relax by the pool for the morning so it wasn't all wasted time. When we returned back to our room after the fireworks, bell services brought everything back to us.
Overall, it wasn't bad switching rooms so many times. It was actually very easy, and we planned everything so that we wouldn't be stuck in the rooms waiting. We enjoyed our vacation and had everything brought to the room when we knew it had arrived.
