Ooooh, it sounds wonderful. I will be doing some snorkling because the girl I'm travelling with is a scuba diver and she's organised to go diving for a couple of days and I'm going to go on the boat and snorkle.

I'm looking forward to Macchu Piccu, and to Cuzco, since I did a paper on Andean history in my degree last year.

You may well get an email as I approach San Fran. It would be great to meet up with people. I was going to say my poor dear friend will be totally overwhelmed, but actually I think she'll probably cope just fine!
