I don't know if this was the cruise we went on, actually. But we did do a dolphin cruise at sunset! It was a crowded boat, that's why I"m not sure. But the captain offered a voucher if we didn't see any dolphins, but that was over in about 15 minutes when we saw the first ones. Some of them were quite far away, but some swam under the bow of the boat. We saw some leap out of the water! The last half hour was more looking at the sunset than the dolphins. It was a lovely time. Don't worry about fixing your hair beforehand, it was a tangled mess!
