Where in the World is TIA Going?

Assuming that I survive this week's grueling schedule, my vacation starts one week from today. Since I'm going somewhere interesting and fun, I thought we'd play a little game, which I will fondly title, "Where in the World is Texas in Africa Going?" Each day for the next week, I'll give a hint about where I'm going and you can try to guess. (No cheating for those of you who know me in real life and already know the answer to this question!)

Hint for day one: It's in another hemisphere.
