Just to update the previous post...did a lot of searching online and in talking with friends / co-workers who have travelled to Costa Rica. The rainforests are supposed to be great to visit. They have arial trams there that do the canopy tours and are small enough cars that you don't feel like someone's blocking your shot (for those of us who are shutterbugs...that can sometimes be a sticking point). Some tours also do canopy trams and then walks on the forest floor so you can see different types of animals. We're getting close - less than 2 months away now - I can't wait for this trip. Will post updates on our return to let others know what we did and how it turned out.
