We plan on bringing a new digital camera for our January trip. We will be in Arenal, Manual Antonio, and the Osa. We hope to do horseback riding, kayaking in the mangrove, and canopy walks, with other activities to be decided once there. We're a little nervous about descriptions about rain, and moisture, and if and how this will affect our camera useage. Should we bring waterproof carry bags? Is it safe/okay to use camera w/out a cover to keep the moisture out? Should we leave the camera back at our hotel when kayaking or going on the horseback ride? Any thoughts?
