I stayed at the Hemingway Inn from September 11 to September 26, 2016 which is considered the off season because of increased rainfall but this did not cause me any real problems because almost like clockwork the rain nearly always fell for an hour or two in the afternoon with the mornings and evenings usually clear. Since many of the tourist points of interest in San Jose, such as the jade museum, are in walking distance of the Hemingway I saw no need spend a lot of money taxis. Also if you take the time to familiarize yourself with the public transit you can save a lot of money. For example, you can take a public transit bus from Alajuala bus terminal in downtown San Jose to the Juan Santamaria international airport for 535 colones (equivalent to about one US dollar) instead of spending 15 or more dollars on a taxi.
In addition to local attractions in San Jose I took a number of day excursions such a rainforest tours (hiking with rainforest guide, ziplining, aerial trams) which usually included a good buffet lunch and sometimes a buffet breakfast depending on the length of the tour. Other tours such as the Baldi hot springs, the Poas volcano and coffee plantations, or a short riverboat cruise where I saw crocodiles, monkeys and sloths I arranged through local tour operators during my stay in San Jose. All of these day excursions included pick up and drop off at the Hemingway Inn.
