The caves were wonderful, the searching for dolphins for an hour was cold, and without results which is ok, just wish I had brought something warmer to wear.. They did provide us jackets if we asked for them, but you have to wait until the boat stops moving to get one. Make sure you use the restroom prior to boarding as its a long time to wait , and of course no bathrooms on the bouncing speed boat..I think we could have been better prepared if they had informed us ahead of time that it gets cold, and prepare us for the elderly that may not have strong bladders..
