Holidaymakers have been advised to book Anzac Day centenary cruises with caution, as the Turkish government bans alternative dawn services in 2015.

Gallipoli historical national park will be closed to all but accredited ticket holders from 12.01am on 24 April until midnight 25 April.

The new structure also prevents cruise ships from anchoring within sight of the battlefield.

The only people who will have access to the sight on the day will be the 10,500 Australians and New Zealanders who won a government ballot for an accredited ticket, plus the 500 VIP’s.

This comes as a surprise to a number of cruisers who were hoping to get a glimpse of the commemoration offshore on cruise ships.

Horizon Cruise Tours owner David Lyons told Cruise Passenger the government’s limit on attendees is a positive move that will help protect the sanctity of the event.

“The number of people going there each year is a testament to how people feel about Anzac Day and Gallipoli, so by restricting numbers the government is protecting the sanctity of the Anzac dawn service and Anzac Day,” he explained.

Mr Lyon said holidaymakers can still get an Anzac experience without attending the commemoration.

For example, Horizon Cruise Tours will operate a 14-day Anzac land and cruise tour aboard Louis Cruises’ Louis Cristal in April next year. Guests will be able to visit Anzac Cove the Thursday prior to Anzac Day and receive historical information from guest lecturers.

APT is also taking travellers aboard Le Soleal for the annual event. Guests will be able to watch the official Anzac Day Dawn Service on large screen in the ship’s theatre and afterwards attend a private service onboard the ship.

And there’s plenty more.

Mr Lyon said holidaymakers should however book cautiously by asking companies to qualify what they offering and ensure it is something that can be delivered.

“Just make sure they’re offering credible and legitimate cruise passage,” he explained.
