This tour should not be offered as a one day tour. You spend around 7 hours travelling, and only 4 hours in Tortuguero actually seeing things. The tour departed around 45 minutes late, and there was a lot of traffic. Arrived back to San Jose just after 7pm.
You do not see any turtles in February, which was the main selling point for me. It does not state on the itinerary that Feb is the off season.
The banana plantation was simply looking at some bananas growing while we drove passed in the bus.
When we arrived, we took a boat to the main village, which was nice for around 30 mins weaving through the lush greenery, but then got a bit boring. On the return boat the sailer really struggled to get us back in low tides, in very hot weather. You spend nearly 3 hours in the boat in total, which is far too long! After lunch you are told to just walk around the hotel for 45 mins (this is away from the nice village part) which is a massive waste of time!
On the way there, we stopped for 30 mins for breakfast, losing more time, this seems unnecessary and took up time which could have been spent in Tortuguero. Lunch was very nice food. Saw one sloth (at the side of the road), some birds, couple of lizards and iguanas, and a baby crocodile - very limited wildlife. NO TURTLES.
We spent 30 mins on the beach, and around 15 mins walking through Tortuguero Village. This was the highlight, and Tortuguero itself seems very nice, relaxed and chilled, a little bit touristy, but less so compared to places like Manuel Antonio, Monteverde and La Fortuna. I wish I would have booked an overnight stay, as I feel it was needed to appreciate the place. The tour guide also speaks multiple languages, which is fine, but means everything is told in Spanish and English, so you miss out on hearing more.
I would not recommend booking this trip as the one day offering from San Jose (certainly not in February). Book it yourself and spend at least one night there.
