Best ship for a first time Transatlantic…..

The simple answer is the Queen Mary II. Why? Its pedigree speaks for itself. Since 1840, this historic company has been offering sailings across the Atlantic on its stately ocean liners specifically built for this type of voyage. The six-day sailings are well known for their traditions, service and style. They aim to recapture the golden era of shipping before the days of flying. Dining becomes a grand occasion while afternoon tea is a formal white-gloved affair.

The most elegant big ship at sea (a liner if you want to be technically correct!), Queen Mary 2 exemplifies the romance of ocean cruising and boasts traditional elegance combined with modern comforts such as a state-of-the-art gym and health spa, one of the largest libraries at sea and the first — and only — planetarium on a cruise ship.
She mainly cruises between Southampton and New York, but also sails to the Americas, Caribbean, Mediterranean and Northern Europe.
