Maybe I'm paranoid, but I would fear getting down there and not having a place to stay or eat. I'm doing a split stay using an AP rate for two nights at POP, then renting DVC points for BWV, then two more nights at POP using the AP rate again. I would want to make sure I didn't have any unpleasant suprises come check out time.
I will call a few days prior to my trip to confirm the hotel ressies, dates, rate, my requests, and that it's paid in full, plus all my PS#, and the confirmation numbers for my tours. I will also confirm they have me booked for ME, so I'm not stranded at the airport.
Of course, I'm also the person who makes at least two copies of her airline E-ticket receipt, AP, room ressies, and PS #s. I have a copy in my check in baggage and another copy in my carry on and I laminate a copy of all my PS to go in my fanny pack or back pack for the parks.
