DH and I aren't seasoned travelers, but we're headed to Costa Rica (Guanacaste area) a week from today. I made reservations through Luxury Link for a resort of private villas that had really good reviews on Trip Advisor and other sites. Other than that, I didn't really think much about doing anything to prepare for traveling there. I figured people go there all the time, no big deal, there shouldn't be much to do to get ready. Right?

Over the weekend we visited with the ILs and they were asking us if we had to get any vaccines or bring any special medications with us, and what we planned to avoid eating/drinking.

We're staying in a villa with a fully-equipped kitchen and we will buying our own food, so I figured standard traveling rules apply - don't drink the tap water or ice made with tap water, only eat cooked veggies, and only eat fruit with thick skin that can be washed and peeled. No problem.

I got curious about the whole vaccine/medication thing and turned to Google and now I'm worried there were things I was supposed to do that I didn't. I'm seeing recommendations for getting vaccinated against typhoid and hepatitis A and for bringing along a "travelers diarrhea" antibiotic.

I'd never heard of having to do any of this stuff for traveling to Costa Rica...did I totally miss the boat and jeopardize our trip? Or is that stuff just overkill? If you've been to CR did you have to do any medical preventive stuff? Help!
