Previously, customers had to make a reservation by phone or by email. Along with the new online features, this is still an option.
The company said the move will expand customer selection and simplify the booking process, allowing its consultants to spend more time creating tailored packages.
Clients will continue to be introduced to staff who will provide support during and after booking.
Managing Director Tony Andrews said: “We are always looking for ways to improve customer service, and the introduction of online booking is a natural step.
“We know that many customers are comfortable using these systems, but it’s important for us to not lose human touch, so our cruise consultants will continue to help on site at all stages of the booking trip.”
