it is a long way, but just 9 hours from DFW, Flight leaves late at night, so you can just stretch out and snooze. arrive fresh in the morning, return is a 1030 pm, so you just snooze all night. You don't lose any days to travel. We have done our date weekends to Buenos Aires and Montevideo, they were easy as the time change isn't much. As long as you can sleep on the plane. But by heading South, we pick up a huge amount of daylight and warm weather.
