Check those boarding passes that your resort prints out for you! They checked in my 5-year-old four times instead of providing boarding passes for each of us individually, so I had to still check in at the ticket counter at the airport to get the correct boarding passes. We stayed at BC and got the boarding passes the morning of our departure. Around 8 am, I went to the airline check-in desk (I was told their hours are 5 am to 1 pm) at the resort and checked in my luggage for the flights; I did not see them again until we picked them up at our final destination. It was very convenient. If they print out the right boarding passes for you and you check in your luggage at the resort, once you get to the airport, you can go straight through security and to your gate. Saves a lot of time!
