My wife and I will be going on a cruise departing from the Port of Buenos Aires in February. If there are no complications, we'll be arriving at EZE the morning of the day before the ship departs, so we will have parts of two days (Sat and Sun) to do a little sightseeing.

I am thinking that we should probably try to spend the night Saturday somewhat close to the port, but maybe that is not the best plan of action.

Any hotel recommendations?
Any activity recommendations?

When the cruise ends two weeks later docking early in the morning on Sunday, we were thinking of flying to Iguazu, departing AEP on a noon departure, spending three nights, then flying back Wednesday, spending one more night in Buenos Aires. On Thursday, bus to Mendoza. On Friday, bus to SCL, then fly back to ATL on Sunday.

Any comments, suggestions, recommendations would be welcome. But especially looking for recommendations for hotel and activities for our short time in Buenos Aires, as well as for the short time in Santiago.
