Costa Rica Twilight Safari and White Water Rafting

I just booked this Twilight river boat trip for our Costa Rica vacation!! Sounds incredibly freaky and fun. I am hoping to see some alligators, sloths, and maybe a squirrel monkey or two.
I also booked the one day Pacuare white water rafting trip, which is "arguably the most scenic rafting in all of Central America." I booked it all through Rios Tropicales. Only 35 more days till we leave.

RiosTropicales Twilight Safari Deluxe

Enjoy this gentle float trip at dusk to see and hear the jungle shift into nocturnal gear.This dusk tour is great for the entire family staying around the Arenal/La Fortuna Areas. Float down the gentle Penas Blancas River looking and listening for the nocturnal wildlife of the area.Experience the Jungle Transform from Day Into NightTheTwilight Safari Deluxe is a unique float trip that offers an exceptional up close experience of nature, and of local traditions and food at the end. You will get on your rafts at dusk as the sun is just starting to fall and enjoy the mystic way the light disappears from the sky, leaving you in the peaceful darkness of the jungle. Our bilingual river guides, trained as naturalists from the Instituto Nacional de Biodiversidad, will begin by explaining to you that more than 60% of the mammals in Costa Rica are nocturnal. With our specially designed lighting system you will then embark on a journey to discover this wildlife. Don’t be alarmed when those red eyes pop out of the banks to stare at you…this is the part of this unique experience that makes floating on a tropical river in the night magical.
The trip begins with a twenty minute drive from Fortuna to the river. . There we will embark on our float down the Penas Blancas at dusk. We'll float for approximately two hours (just the right length for the youngsters.) Our naturalist guides during this time will help point out and talk about the nocturnal wildlife of this area. On your float you will have a chance to see (or hear): the Common Opossum, Common Gray Four-Opossum, Brown-throated three Toed Sloth, Hoffmann’s Two-Toed Sloth, Long-Nosed Bat, mantled Howler Monkey, Yellow-crowned Night-Heron, Spectacled Owl and lastly, the American crocodile. You'll see plenty of baby crocoodiles, no longer than a foot. Your guide will focus on the animal and plant behavioral transitions from day to night.
At the end of the river portion of this trip guests will arrive at a local working farm where the owner is a well-known Costa Rican horse breeder and trainer. Their daughter (already a competitive rider!) may share a traditional style dance for you while you sit down to enjoy wonderful native food, all fresh from their farm. His wife makes delicious typical style food like yucca bread, home made cheese, sweet fried plantations, and serves these treats with our famous coffee made the old-fashion way in a special “sock”. Fresh juice is also served. The barbecue is revved up to make tortillas filled with fajita meat. Upon request, horse shows are also available. The trip concludes with a twenty minute drive back to Fortuna.
