Riviera Travel has dropped Ireland from its UK departures this summer.
The July sailings previously included a call to County Donegal, which has now changed to Belfast.
This means all ports on the itinerary are UK-based and passengers can book “without any travel limitation concerns”.
The four British Isles cruises by 158-passenger MS Seaventure, refurbished in 2019, will now feature Scotland’s highlands and islands.
The eight-day itinerary departs from either Edinburgh or Greenock and has a port stop and excursion included every day, taking in Aberdeen, Inverness, Orkney, Oban, Outer Hebrides and Belfast.
Tours include trips to Loch Ness, Balmoral Castle, Titanic Visitor Centre, Callanish Standing Stones, and the Neolithic Ring of Brodgar henge and stone circle.
Free parking is available at Edinburgh’s port of Leith with a shuttle transfer to or from the ship at Greenock.
Prices start at £1,999 per person, based on two people sharing a cabin, including full board, tours, visits and port taxes. Cabins are also available for solo occupancy without a supplement.
Seaventure has 82 sea-view cabins with a choice of balcony, panoramic window or porthole.
The vessel has fitness suite, sauna, heated saltwater pool, expedition theatre and library.
