San Jose for a couple of days

Summary
Costa Rica is a wildlife wonderland. My recommendation is to get to the spots in the country where you can enjoy this wildlife rather than spending time in San Jose which is a generic unattractive Central American city
If do have to spend time there, the Teatro Nacional is worth checking out, but other than that I’d suggest leave quickly / avoid

Score Detail
Background - how many times have you asked someone what a travel experience was like and the response was "amazing" or "awesome"? That response is nice to know, but it makes it hard to differentiate that experience compared to others. That is exactly what these scores are trying to do - differentiate the experience by giving a score out of 10 based on 6 categories and then giving an overall experience score
This overall experience score is calculated by: take the highest of the "Culture" or "Nature" score (1-10) + "Fun factor" (1-10) + "Avoiding the crowds" (1-10) + highest of the "Unique" or "World Famous score" (1-10). Then convert into a score out of 100
Extra detail - the logic being that I find all of the 6 individual scores important, but I don't want to mark an experience down just because it doesn't cover both "Culture" and "Nature", or because it isn't both "World Famous" and "Unique". Take the examples of Safari in The Serengeti and walking through Rome - they both appeal at opposite ends of the nature / culture spectrum, and you can have a fantastic time without needing to appeal to both sides. So, their overall scores aren't penalized for their lack of one or the other, and I've done the same for "World Famous" vs "Unique". But . . . I do think that the "Fun factor" of an experience is important, irrelevant of other factors, and so is "Avoiding the Crowds" (or where there are crowds that add to the experience). So, both of these scores are standalone
