For me, the worst part is getting up, getting the taxi to show up in time to take us and all our crapola to the airport, and running the gauntlet to get checked in, our bags checked, and getting through the TSA rigmarole, all in time to board the flight and on a couple of hours sleep. From there on it's not stressful; it's a bit of a crunch at the Cozumel airport with Immigration and Customs to deal with, but I am there on the island and there's no time pressure. If it takes an hour to get to my hotel (it usually doesn't), it's no big deal; I am there for a couple of weeks. The thing I hate isn't the time it takes to get somewhere, it's the stress that comes from being in a hurry. I don't do that to myself when it isn't necessary.
