It is important to make sure there is flexibility with your return ticket / date in case of delays in Antarctica. You can either buy a flexible ticket or a ticket that you have the ability to change for a small fee. Some people book their return flight for several days after they are due back from Antarctica.

Where will I stay in Punta Arenas?
The recommended hotels are currently the Diego de Almagro and Rey don Felipe (now called Almasur Punta Arenas). Competitors can also choose from a range of other hotels with prices from US$50 - US$300 per night depending on quality and services. Dreams Hotel is probably the highest end hotel in town. When booking a hotel, please keep in mind that your budget should cover the possibility of being stuck in Punta Arenas for several days before the jet actually takes off for Antarctica.
