Optionals On every itinerary, we offer a range of optional excursions that allow you to further enhance your experience should you so choose. These are purchased when you are on your trip, via your Trafalgar Travel Director. Depending on the region visited these can be paid with cash or credit card. A reduction of 25% of the cost of the Optional Excursions is offered to all children under the age of 16 years at the time of travel. Please Note: This discount to does not apply to North America optionals, as they are already discounted.
