As you see, luggage service halts between 10pm-5am(ish). The thing to keep in mind....bags can be expected in your resort room, up to 3 hrs after you checkin at your resort. So, if you arrive at MCO at,say, 6:00pm, you can expect to be at your resort by 7:30. This means your bags might not get to your room until 10:30. I would be very tempted to leave be yellow tags off the checked bags, and get them myself at baggage claim. Then, they go to the bus with you, and stowed beneath your bus and handed to you when you arrive at your resort. You should plan on tipping a dollar per bag since the driver has helped you with them.
