When our cruise (Carnival Liberty) arrives in Limon, it will be the first week in October. Will the water be too cold? Have any of you ever done this excursion through Carnival? According to Carnival's website, it is a one-hour air-conditioned bus ride to raft the dam-controlled ReventazÃƒÂ³n RiverÃ¢â‚¬â„¢s rapids. Then we "return to the Rios Tropicales Center for a delicious Costa Rican lunch and refreshments." Are you supposed to bring a change of clothes? Are you soaked afterwards, and freeze on the bus ride back to the ship? Is there an opportunity to take pictures with our own waterproof camera? Do they have photographer who sells pictures to you? How much? This seems like an excursion that is probably worth booking through the ship. I intend to do so unless someone convinces me that it is easy to do through a local, and no chance of missing the ship, and much cheaper.
