We stayed here over Easter week in April with two kids. We were worried about it as it was such a long trip... Bus ride, boat ride... But in fact the getting there was half the fun and even the kids, who are not great travelers, loved it. The hotel arranges everything, picking you up in San Jose, taking a bus ride through very scenic roads and then the boat. Tortuguero is gorgeous.. Canals, mangroves, jungle, with monkeys, birds, caimans. Very relaxing boat rides in the canal. The cabins are rustic but very comfortable, and you really feel remote.. At night you hear the sounds of the jungle and the waves crashing. On our balcony we saw fords and in the grounds, lizards, iguanas, snakes. Kids were in heaven! Our tour guide was really nice and went out of her way, her name was Cynthia.
All in all a unique memory and would definitely recommend this if you are looking to get away from it all.
