Amazing country, with luscious nature and great wildlife. Whereas San Jose is not so interesting, the Central Valley has a lot to offer, and the Caribbean coast is wonderful. The organisation of the trip went smoothly and all went according to plans.
Responsiveness, helpfulness in gauging the trip
Be more assertive with their advices =). Which is very tricky to do, but I wish I trusted their initial suggestion rather than asking for something different, that they organised for me, which was probably not worth it.
Spend the least amount of time in San Jose. It is just not worth it considering how beautiful the country is. Irazu volcano is underwhelming with a minibus that brings you to the top.
