on a sour note, the west coast of CR has been experiencing an outbreak of dengue fever in the last 4 years, to record levels. The government launched a effort in 2011 to combat it but the levels of cases per year in the last 3 years has been 11000, 26000 then 49000, even with the governments efforts (which to me judging by the numbers is not working well). we love cr but will not go back as that disease can be serious, especially if you have any other risk factor. google it. Tourist sites usually dont mention things like it.
