Booking- We booked directly with Ponant's US office. Office staff were generally poorly responsive. Emails and voicemails were not were not regularly responded to and it was difficult to reach a person when calling. The office also apparently neglected to forward information regarding the dietary restrictions of one of our party to the ship.
Charter flight to Ushuaia/tour of Tierra del Fuego- We spent several days on our own in Buenos Aries. Since we'd heard flights to Ushuaia can be unreliable, we decided to pay the premium and reserve seats on a LAN flight chartered by Ponant. We were given instructions to be at AEP at 4:30 AM, where we'd be greeted by representatives of the cruise line who would get us our boarding passes and on the plane. We arrived at the airport at 4:20 to find no representatives and no indication what to do. Only the heroic help of the LAN representatives got us to the gate--the plane was half boarded at the time. Since it was a charter flight, there were no published flight times on the LAN web page, and the departure time had been moved up and we received no notice.
Once arriving in Ushuaia, we had about a half hour to explore the town before our bus tour of the national park and traditional lamb BBQ. They had a bus specifically for English speaking guests. The bus tour was run by a local agency and we enjoyed it, although it was a pretty whirlwind trip and in retrospect would have enjoyed spending more time in Ushuaia.
We were happy with our cabin. The divided restroom is a little bit strange--it'd be nice to be able to get to the sink immediately after using the toilet. As mentioned in previous reviews, the shower/sink half of the restroom has a window to the rest of the cabin with a sliding door to close for privacy. It'd be nice to have the control of the privacy screen on the inside rather than outside of the restroom. We also would have appreciated one or two more electrical outlets. )There were two plug outlets in the main cabin, and one in the restroom). The 3rd floor balconies have a different door style--swinging rather than sliding. The balcony is also different--solid metal sufficiently high that you can't really see much when sitting (unless you're really tall).
