Thanks to all at Contours for a wonderful trip to Brazil and Buenos Aires. The hotels were all wonderful, activities suggested were informative and fun and the transfers went well. There were problems with airlines changing things and suddenly requiring forms to be filled in on-line which proved impossible but Ben fixed it all promptly. The local operators were also excellent to deal with when I wanted to change some things while there. Will definitely be using them again for my next South or Central American trip.
