When I was there in May, POP was the first drop off. FYI: I arrived at MCO about 9:42am and was on the bus in less than 15 minutes and leaving the airport in about 20-25 minutes. The bus was no where near full. This was on a Friday morning. I had gotten a seat three rows back from the driver and was one of the first to get checked in at POP. My room was ready, I dropped off my carry on, and I was in the park for lunch. When I left POP on a Sunday 9 days later at about 3:00pm the bus was again no where near full and we didn't stop anywhere else on the way to the airport. I'm not sure why as there were plenty of seats available on the bus.
