Hi smep! Isn't the Peru adventure just wonderful? It is really so worth it!! Bobo, I kept an eagle eye on my 10 y/o daughter since she is probably the most I am worried about. The funny thing is, only grown ups got sick in our group. Nothing bothered the children - the altitude or the food. They were buying street food and all and they are still alive and kicking the next day. It's amazing how much stamina and energy these kids have... which we did way back when. My daughter got even splashed on the face while in the river and she rode on a different boat from us since she wanted to be with her friends. I gave her strict instructions not to drink any water and she told me she immediately spat out whatever was in her mouth. Thank God, she is not prone to gastroenteritis, I can count in my one hand the number of times she has had it. My hubby is a different story and same thing, he didn't want to deter his trip and hacked it out. Poor guy, he had chills and fever the time we went to Moray but I'm glad he turned out okay.
