Hey Murray,
I see you are just flying to Ushuaia.... Lovely place! Say hello to the penguins for us! Don't forget to look out the Port Window on your approach, you'll get a lovely view of the glaciers! (One of the most spectacular take offs I have ever had was from there, breathtaking scenery!) Oh by the way, there is a fantastic little chocolate shop, you can't miss it, there are only about 5 shops there!
Have fun.
