As for Mayan ruins, at the moment we're set to do Lamanai in Belize. But we could switch once we're on the boat. David insists we visit at least one, since it's my first time in that part of the world. He visited Chichen Itza in the 70's.

The fish sounds great, will look for it! And I will remember to avoid ice cubes and stick to beer!

Arlene, I certainly remember your account of your (mis)adventure on Santo Tomas! And thanks for all the advice about eating. It's mostly about foreign bugs that we just don't have in our systems--I managed quite well in Bombay for a week, with an experienced colleague advising and vetting everything I ate, so if I know what to avoid, it's fairly easy. I'm thinking I'll be safe with fish, rice, beans and beer! How about shrimp?
