Thanks everyone!
I'm having a great time! Really good. And as to weight - well, I don't have to worry about gaining. Although I ate really carefully yesterday (I have a bit of a weakness since my first trip here 26 years ago gave me salmonella)today I felt really ill and had to miss the excursions. I felt a bit better in the afternoon, so did some great solo stuff. Hope to be fit for travel tomorrow though. At any rate, I'm only going to be eating a very little, very plain food. Ah well!
