Hi, I'm planning to travel to Corcovado National Park end of December. Is it's possible to make a reservation (entrance fee, guide, tent) at the reservation office in Puerto Jiménez the day before to depart the following day? Does anyone have an idea of the price for a guide. As I'm travelling on my own, do you think it will be easy to find a second person to do the trekking? Many thanks. Cigalou
