We are doing a similar thing. I rented a one bedroom BWV from someone on the TUG boards for our upcoming spring break. We arrive on Saturday evening, but the rental is Sunday to Sunday (worth the savings though!). Since we're not doing much when we arrive, just relax and have dinner, I booked us at the Swan the night before. It's right next door, and I had Starpoints so it's free (just have to pay the stupid $20 resort fee and $15 parking fee). I figured we'd go check in early and make sure our magic bands are all set up then leave our luggage and enjoy the day. Then we plan on unpacking later when the room is ready and I'll grocery shop.
