We are honeymooning in costa rica in June, I'm wondering when to book the excursions we want to do...now or when we get there? Will the be booked if we wait? I'm a little nervous about booking them earlier because of the rainy season there. Also, I don't know if this a stupid question, but how would you book them in advance, can you do it online? Obviously I don't really want to be calling costa rica Thanks!! :
