Thanks Sam and Gaucho.

1. We are flying Skyteam, so the LAN pass isn't an option.
2. Re: Bariloche - My wife and I love nature (more than skiing) and like the possibility of hiking / being stuck in a cabin for a few days.
3. Butterfly is noted, as are your other food recommendations. We are foodies and are looking forward to lots of good meals.
4. We do love wine, but are more interested in drinking it, then touring vineyards (this is based on our experience in Bordeaux, Sonoma and Napa), but given some good reasons we could change our minds.
5. We've heard some good things about Santiago.. are you saying 3 days is way too much?
6. Travel times have not been incorporated as I'm not sure on the method.

thanks,
scott
