My wife and I took the 3 1/2 hour, evening Grand Tour. Boat was only about half full, so we had plenty of room on this trip. There was rain and some lightning during the trip out, but the captain did a nice job missing the worst storms and he kept us entertained with his stories of the islands. When we got to the sea caves, the captain put the front of the boat right up aganist the rocks so we all had a close-up view of the caves...great for pictures! We packed a lunch and a bottle of wine, which kept us occupied during the trip out. As some reviewers have said, the sea caves are worth seeing, but the trip out and back is just a faraway view of some of the islands. Don't take the tour if you are easily bored. It's not a "party" cruise on your uncle's cabin cruiser. It is what it is...a nice smooth boat ride, and if the weather is nice, you can sit outside. You can enjoy a picnic lunch if you like. You will learn a few things about the area, and the scenery is wonderful.
The crew was terrific.
