Hi- seeking advice for a 1 week trip in January this year. I went to Costa Rica this spring loved it. Went to Arenal, Monteverde, and Maneul Antonio. Originally was planHning to return to the latter 2, but also open to exploring other places. I realize 1 week does not leave much time, but sadly it is all that my schedule allows. Ideally looking for something warm that you could get to without renting a car (I am also from Boston and feel that I am following in your footsteps!) Thanks for your help!
