Thanks so much for the reply. My major interest is Panama and Costa Rica too. I am busy reading McCullough's "The Path Between the Seas". It's a wonderful book to read especially before the trip as Panama comes alive and I can really understand the drama behind the Canal.
I'm probably going to go with the Embera trip or Gaten Lake Safari. If I was alone I'd go through the entire canal, but I have family depending on me.
Thanks again for the kind reply. Can't wait to go.
Thanks for the tip about the rain!
