Find Your Cruise
Very expensive. Walk down the gangplank and do a deal with the local taxis. Go with two other people, you will see exactly the same as you would on the ships tours, and it will save you at least 80% of the price. Unfortunately, the organised ship's tours are a rip off.
The Ocean Village web site will show what tours are on offer and the cost of them. You can also book for any of them on lin.
