The nice thing about Continental is that is flies directly to and from Merida almost every day.
The evil thing about Continental is that the one and only morning departure leaves at 7:00 AM. Which means that you have to be at the airport at 5:00 AM or 5:30 AM at the latest. This means leaving your Merida house at 4:30 AM or so, depending on where you are, which means getting up at 4:00 AM.
Sometimes I get called to take people to the airport on this little trip, but mostly, people prefer to take a cab, simply because it´s cheaper. My service is about personal driving and there's not much in the way of a 'drive' on this airport trip so I can understand when people are shocked that I charge what I do.
I do, however, provide the best cup of fresh, industrial strength coffee on that short trip that you will have all morning.
