If you decide to cancel the tour please send me an e-mail or give me a call at least 24 hours prior of the tour. In that case no cancellation fee will be imposed. Otherwise, if your ship docks at the port and you do not show up for the tour on the date agreed, your credit card will be charged by the whole amount. Of course, if for any unforseen reason the ship does not dock at the pier then there will be no charge.
