It was a bit chilly the day we took this cruise, but the boat does have an enclosed climate controlled main deck. Even so, we sat on the upper deck and enjoyed the cooler weather. It was easier to do, since they provided clean and warm blankets to wrap up with during the cruise. The loud speaker didn't work well on the top deck, but the captain provided very informative information about the surrounding area and the dolphins. We saw quite a few, but unfortunately none really close to the boat. Even so, we had a lovely time and highly recommend this cruise with Vagabond.
