Hey Sabira!

Thanks so much for your questions! We currently offer discounts for Costa Rica day tours only so unfortunately we can’t help with a discount for the 2-day (i.e. overnight) rafting trip. For the Manuel Antonio National Park, this park doesn’t allow overnight stays/guests, so it would be best to plan your visit as a day trip. The public part of the park isn’t all that large; most people come for a few hours to hike the trails or relax on the park’s beaches. If you want to visit the park over the course of two days, though, you certainly can–you’d just need to pay the entrance fee twice (once per day) in this case. 🙂

Pura vida!
