Just information for those who don't know (or are seeking information later on), I did a chat with DCL and they amended our MCO to Port Canaveral transportation to Hyatt Regency Orlando Int'l Airport to Port Canaveral. We booked the Hyatt through Hotels dot com and there was no added cost to the Hyatt transfer over the regular airport transfers. I'm pretty excited to not have to drag our luggage through the airport.
Well, you'll still need to drag it over to the Hyatt when you get to the airport. Better than doing it twice, though!
