Royal Caribbean say the phones are ringing off the hook at its customer-service centre – and what everyone wants is a berth on Ovation of the Seas.

The line claimed it received more than 200 per cent more calls on the day bookings opened.

But when the highly anticipated vessel – the largest to be homeported in Australia – gets to our shores, she’ll have to face off two other popular ships: P&O’s Pacific Dawn and Princess Cruises’ Emerald Princess.

So how does the Ovation stack up?
