Hi! I recently did a long trip through Argentina, what a great place! I visited the Patagonia glaciers and Ushuaia, as well as Bariloche and Mendoza. I wanted to go off the beaten track so I looked for an agency offering something different. They offered private driver-guides, accommodations at exclusive hotels and a great overall service. If anyone is interested in doing an original trip through Argentina I recommend Argentina Excepcion, their site is http://www.argentina-excepcion.com .  I'll be glad to answer any questions, and I'm looking forward to sharing my experience! Cheers!
