Mid march is a great time to get away from a long dreary winter. If you seek a little adventure then I would suggest you sail on the 16 night Andes and South America cruise.
We opted to fly in to Santiago and take the Princess transfer to the port of San Antonio. We rode on a modern air conditioned bus. The ride was about an hour and a half. We had no washroom so you may want to use a facility before leaving the airport.
We had a smooth embarkation. The life boat drill was held in the a public area with a lot of other passengers. We did not have to take our life jackets. I made sure we sized our jackets to our torsos. One less thing to worry about in an emergency.
