This was part one of a Back to back cruise.
We flew in to Buenos Aires a week early so that we could see Iguazu Falls. After all, if you are traveling this far, might as well see other spots.
We got a great rate (Premier Class) on Aero Mexico from Orlando to Mexico City to Buenos Aires. A word of caution: I booked the flight online properly, and when I did a periodic check to make sure it was still scheduled, it had changed to round trip Orlando to Mexico City to Orlando. After a nervous phone call, we were rescheduled on the next day's flight.
This cabin was very quiet. No noise, no vibration. During the cruise, the crew used some sort of hose to wash the window. That was very helpful. The attendant was very meticulous and caring. She had 16 cabins to take care of. Even though we were in the cabin on a B2B for 29 nights, we still had plenty of room to move around.
