All the advice you have received is good, in my opinion. The Chilean
Fjords are spectacular and probably the least publicized area in the
world. Except for the large cities, you will be well advised to take the
tours arranged by the ship. Ushaia, PuertoMott, Point Arena etc. are
all very small and have extremely limited tour options. You are really
in for a treat. ENJOY The South Atlantic and the South Pacitif can be
a little rough, so don't forget your Bonine--and some warm clothes.
