Do you have any suggestions for an itinerary through Panama and Costa Rica in August? I am flying in and out of San Jose, but I definitely want to see the Canal (I'm an engineer - I love big infrastructure). I am looking forward to wildlife watching, birding, rafting, seeing coffee and banana farms, a little beach time, and snorkeling if possible. Are there places that are less humid? I don't want to rent a car. I'm open to taking a short plane trip if that helps save time. How are overnight buses?
Thanks so much in advance!
