The excursions marked in bold are optional and can be booked individually on board at extra cost or can be pre-paid as an inclusive package (prices available on request). All other guided tours as described in the itinerary are included in the price. Arrival and departure times are guidance times. We reserve the right to change itineraries and excursion programmes. If a route cannot be travelled due to low/high water or a ship defect, the shipping company reserves the right to take passengers on this route by bus, to accommodate them in hotels and/or change the route. In certain circumstances it may be necessary to change to another ship.
