First time cruisers - we are going to spend an extra night after the cruise at a hotel at MCO before flying back home. This saved us over $500 on airfare! Anyway, I am wondering what happens to our luggage when we disembark from the ship if we use Disney Transport to get back to MCO? Does Southwest offer portside check-in and can we just let our bags go onto the airport without us while we head to a hotel for an extra night with just a carry-on?
