The day before departure, you should get a packet hanging on your door. It will have all the information as to your bus time. The time given is FOR DEPARTURE of the bus, not when it will show up. There have been more and more reports of buses getting folks back to MCO later then normal because there have been stragglers and folks not ready to board the bus. Many times, you will just be out of luck as the driver wont wait for you, or isnt supposed to. If they do, it throws off the timing, and it can start to add up. You should be at the bus stop with everything you need, ready to walk on that bus, at least 15 minutes prior to the departure time. We usually show up closer to 30 minutes before, just because. If you need to retrieve bags from bell/luggage service, plan ahead for that as you can have a line there also.
