Just Bring Yourself (and Updated Medical Records)
The endlessly agonizing question for surfers on vacation is always whether or not to bring your beloved board. Or two. Or three. And it is tempting; it's your board, after all, and you know it and love it. (Not to mention it tips off everyone that you are a Serious Surfer.)
But crating around boards is no small task. First off, if you're a serious surfer you're probably going to be doing a fair bit of traveling around the country. Rental cars won't always be equipped with racks, and beware airline baggage rules. If you're using intra-country air travel (or traveling by air to nearby countries on your vacation), the restrictions vary. Some commercial lines don't allow boards as baggage due to weight or space restrictions. Plan ahead so you're not kissing your beloved board goodbye at the gate.
Although it's not necessarily just for surfers, be aware that some regions of Costa Rica are at risk for high malaria incidence. Talk to your doctor about where you're going and discuss whether an anti-malarial drug or any other vaccinations should be administered.
