We're going to CR with teenage kids in the summer. Once-in-a-lifetime wildlife trip, going to Tortuguero, Arenal, Monteverde, Manuel Antonio, Uvita and Osa Peninsula. I'm incredibly excited, but never done a trip like this. It's booked via a tour operator so don't need to worry about transfers etc, but would love any tips for practicalities (things to take, bear in mind etc). NB changing flights in Miami.
I'm also just a little perturbed by warnings in the Rough Guide about sharks, snakes, Dengue fever, rabies, crocodiles, rip tides etc. Is this a real worry? I've spoken to a few people who've been and just said it was great, so I'm hoping it's actually fairly safe in practice?!
