DH and I are considering a bike trip this coming Jan or Feb, likely to South America (Argentina/Chile) to enjoy the opposite season. We desperately need vacation, we prefer active vacations, and the bikes seem like a great way go to. DH has been a cyclist for years and we're both tri folks, so we figure our fitness level is fine for the sorts of trips we're looking at. We're eyeing group tours with 15-75+ miles of riding daily (at least 2-3 options for length each day) with interesting lodging and the promise of fabulous meals.

Anyone done this, especially with groups like Backroads or Butterfield and Robinson? What would you have done differently? What did you love? Please share!
