Car: repeat after me: 4x4. 4x4. 4x4. 4x4…
either that, or as option 2: pickup truck. Pickup truck. Pickup truck…
Costa Rica is beautiful. It was bad for my health but I’m not sure how much of that was stress. It also boasts horrid roads. Repeat: 4x4, 4x4, 4x4… And watch those tires, they need to be replaced relatively fast.
The Valle Central, where most people live, is cool. Oh, wait, where are you from… OK, it’s COLD, by your standards. Also very rainy: you don’t get all that green forest without rain! In the Valle it can rain pretty much on any day of the year.
The Caribean coast is very hot and humid.
I lived for 6 months in Guanacaste (the NW coast, on the Pacific). The best time to be there is supposed to be Dec-Jan: the roads have been fixed (maaaybe, last year there had been so much damage that they simply couldn’t fix everything), the sun is out, but because the winds come from inland it’s not too hot and not very humid.
The wet season is May-October. The trees get greener, the roads get bumpier, the tourists grouch because they wanted sun. As soon as the sun gets out for a week, things start turning from bright-green to coffee-colored.
I hope you don’t like fish: in Costa Rica, fish is “something you get out of the water and sell to Spain”. There’s a local dish called ceviche which is a maceration of fish bits with cilantro and other herbs, but personally I don’t trust a fish dish made by people who don’t know the difference between a cod and a sardine.
Meat will be chicken or beef. Sheep is something they’ve seen in books; I’ve had people ask me how big they are. You’ll be able to get pretty much the same veggies you’re used to in the States (didn’t see okra, for example, but mostly the supermarket rack looked the same to me in both). A bit short on fruit; again, they grow blackberries and raspberries but it’s mostly for the foreign markets. The apples were canadian stare
