Your p/u time will be around 3:30ish. You could book a car service, but that will cost about $60, plus tip, and will gain you, maybe, 45 mins. Many think that they can leave the resort 2 hrs prior to flight departure, but that gets you to MCO 90 mins before your flight. If there are any issues along the way, or security is an issue, you could end up stressing. Even when I book a car service, I ask to be picked up 2.5 hrs prior to departure.
The other choice might be taking dme back late the night before and checking into a hotel at the airport.
