There has been a delay in the arrival of the MS Artania into Killybegs tomorrow.
Hundreds of people are due in the port to see the massive liver arrive.
The cruiser, which has 1,200 passengers and 800 on board, was due to arrive in Donegal at 8am but will not now arrive until 11am.
The ship will be leaving at 8pm as scheduled.
Many of the passengers on board, most of whom are German and Swiss, will visit various sites across the North West including Glenveagh National Park, Glemcolmcille and Sligo.
Tourism chiefs are hoping many of those who enjoy a day long break to Donegal may return on longer trips in the future.
