Yes, they would be able to move the bags to the new room. I agree that sometimes the extra cost of the Disney room is worth it just because it's so much easier to move to your booked resort the next morning. We drive to Disney over 2 days and we typically spend the second night in a hotel about an hour or so before Disney. This year (in June) we made really good time on the second day of our drive so if we had stuck with our original plan of spending the night about an hour away from Disney, we would have stopped driving at about 4:30 in the afternoon. That just seemed silly to us so I quickly booked a room at Disney for that night (I was lazy and just booked directly with Disney because I didn't want there to be any issues when we arrived). Our week-long reservation was for a suite at AoA, so I booked a room at Pop Century (there were only 3 of us that night) for the night. With tax and the "additional adult" fee, it cost us $301. We paid $255 for a room the night before in Fayetteville, so this wasn't really a big deal. The nice thing about being on property that night was that it allowed us to ease in to our vacation -- we had dinner at the resort, bought our refillable mugs, and then headed to DS to see the drone show. We only took our overnight bags into the PC room, so the next morning we slept in a bit (we didn't get back to the room until after midnight because we went to the 10:45 drone show), had some breakfast at the resort, and then threw our overnight bags back in the car (that was parked just steps from the building we were in) and drove across the parking lot to AoA and went to our room there. We were in our room and unpacked before lunch. The ease of everything that morning and the bonus of getting something checked off our "to do" list the night before made it totally worth the extra cost (for us) to stay at Disney that night rather than an offsite hotel. YMMV.
