We are going to hear the same old information over and over about The Sims 3 World Adventures for awhile or at least until we see a new location.  So just a forward warning letting you know!  Until then, check out this article written by HookedGamers:

Three exotic locations are available for you to travel to, each a parody on existing locations in France, Egypt and China. You will experience rich culture in Champs Les Sims, venture into ancient tombs in the pyramids of Al Simhara (you can become a Mummy in Al Simhara!) and master martial arts in Shang Simla.

The three destinations are expected to be about the same size as Sunset Valley in the main game, so certainly worth the simoleons you will be spending on the flight there. Upon arrival, it is up to you whether to just enjoy a quiet holiday and meet the locals, or to be a little more adventurous. Obviously the most fun is to be had when you choose the latter.
