While I wouldn't personally want to do just 1 night at each resort, because it is a bit of a hassle, here's what we did on our last trip.
In the morning, we checked out & took our stuff to luggage services. They tagged our bags to the resort they were going to next & did everything else for us. When we checked in at the next resort, we asked about our bags. They usually didn't arrive until after dinner time, so any thing you may want during the day, you'd want to keep with you. Swimming may be hard for that purpose? It maybe only added 10-15 minutes to each morning so it wasn't a huge hassle. But if you like to take breaks during the day, you may not have that option if your new room is not yet ready.
Tickets - we have AP's but I did have a hopper on that trip that I needed to upgrade. We just activated our tickets & I upgraded at guest services, I had no issues on the rest of the trip.
I'm not sure about the dining plan, I thought there was a minimum of 2 nights? I could be wrong?
