Hotel in Calafante, Argentina, although lovely and a beautiful town, is located adjacent to hostels. The noise from voices and motorcycle engines went all through the night of the 3 nights we were there. SLeep was impossible. Random assignment of seating on flights from Miami to Chile/Buenos Aires to Miami was miserable. We could not sit with our travel companions, we had no choice on where in the seating chart, even when checking in well within the 48 hour allowance. Connections in Miami en route home were thus made very stressful. We lucked out with a terrific tour guide for the majority of the trip that made the experience excellent. Tour guide in BA was just ok. Balance of activities, selection of what we saw, and modes of transportation were all handled well.
