The €343m super cruise liner was led into Dublin Port yesterday morning by tug boats and drew stunned looks from early risers lucky to catch sight of her.
The arrival of the 109,000-tonne, 290-metre liner marked the launch of Dublin Port's annual cruise season during which 90 cruise liners will visit the city with an expected €50m boost to the local economy.
On board the liner were almost 4,000 passengers and crew.
She had sailed from Greenock, near Glasgow, and after her stay in Dublin will travel on to Falmouth in Cornwall as part of a European cruise.
The 'Grand Princess' was built in 1998 in Italy -- at the time the largest and most expensive passenger ship ever built.
She has 17 decks, including a wrap-around promenade deck. Each of the 170 staterooms has its own private balcony and 24-hour room service. The ship has four swimming pools and a nine-hole golf course.
And for passengers feeling romantic it also has a wedding chapel.
