I too have been looking at a South America cruise. Please take a look at Celebrity Infinity on Dec. 9. This is a 13 night cruise fron Buenos Aires to Valparaiso. The following prices include AIR from Miami & transportation from airport to ship then transportation from ship to airport. The prices are: I/O/B 1944/2193/2493 per person total. Check to see if you may be able to do better by booking air on our own.
Let me know
