Cortrans leaves from the port at 8:30, 9:30. and 10:30, for $30. They don't wait until the buses fill up. they pre-book, so when everyone for that departure shows up, they leave. These are 15 passenger buses, not the big "greyhound" type buses. I use them for all my MCO departures. It's a nice husband/wife owned company. I'm not sure if we're allowed to post links here. Just google Cortans Orlando, and their site will be at the top of the results
