Kayak periodically sends me some unbelievable travel deals.  This week, they highlighted an 8 day trip to Rio, Iguazu and Buenos Aires for $1499.   This includes airfare from JFK (other departure cities also available), connections and hotel.  This package is just one of the many offered  by Latin Destinations.  Their web site is very well designed and easy to navigate.  Customizing your trip and viewing alternatives is a cinch - just click on Design Your Own Trip.
