Relax and Enjoy yourselves!

I would say you are pretty much dead on in your recommendations...salads are a bit tricky based on where you buy them but in most cases these days almost everyone use the same techniques to clean their products and use some antibacterial agent in the wash...I'm someone that has been all over Mexico and eat food at small, out of the way places and barely ever get sick. But it can happen and did a couple years ago...Often, it's a case of too much of a good thing and that applies especially to fruits in all forms. A lot of folks will find the fruits here more more flavorful and will eat more of them, including fruit juices and fruit plates. As fruits here being picked fresh and not like what you buy generally in N/A stores, they are also loaded with vitamins/minerals and it's easy to overdo it and get some gastro issues from that...The first few days, eat light meals and stick to fresh food and go easy on spices and use plenty of lime juice and you will do just fine...Eating some yogurt daily is a good recommendation...
