Great group of folks and a really cool experience! Be sure to book this early in your trip. We actually did not have any Mantas show up our first night out. Rare, but it happens. Luckily, they will re-book you to try again at no cost. However, they are usually booked a couple days out. On our second outing, they did show up and it was really cool. One even barrel rolled right up under the board right by us!
