Community Members....there was an excellent article in the Sunday (09/30/2007)New York Times Travel Section on methods to increase savings when booking certaintypes oftravel involving rental cars and some air travel(nothing beats LL for their hotel and resort packages):
When we traveled to Venice, Italythis past summer,we used Hertz.it instead of Hertz.com and saved $24 @ day on the same category of automobile......they ask for your country of residence, but itnever became an issue at thepick-up point.....as a matter of fact, we showed them our Hertz#1, begged and smileda little and ended up with a double upgrade (more fun driving that Mercedes/Benz) at the same lower price.
We just had a travel agent in Santiago, Chile buy air tickets for our use inside Chile and Argentina for early 2008 and we saved more than $200 each (over the same flights we first priced on theairline's .com site). The travel agent booked and paid for the flight and we paid the agent directly by credit card.
The article is very detailed and does offer some caveats. Good Luck...
Our little local paper also carried the article. The one case I read is that the person doing this could speak another language. That is definitely a plus! That is interesting to price out your hotels/cars/air on the foreign equivalent website. Just be careful that you know the rules.
You can also do really well by using the local regional version of expedia/travelocity/orbitz. It can take a little searching, but I'm sure the community at LL can assist. In China for example it's www.ctrip.com.
