11 nights, from Southampton

Southampton is the largest city in the ceremonial county of Hampshire, England. It is 69 miles (111 km) south-west of London and 15 miles (24 km) west north-west of Portsmouth. Southampton is a major port and the closest city to the New Forest. It lies at the northernmost point of Southampton Water at the confluence of the Rivers Test and Itchen, with the River Hamble joining to the south of the urban area. The city, which is a unitary authority, has an estimated population of 253,651. The city's name is sometimes abbreviated in writing to "So'ton" or "Soton", and a resident of Southampton is called a Sotonian.

Significant employers in the city include Southampton City Council, the University of Southampton, Solent University, Southampton Airport, Ordnance Survey, BBC South, the NHS, ABP and Carnival UK. Southampton is noted for its association with the RMS Titanic, the Spitfire and more generally in the World War II narrative as one of the departure points for D-Day, and more recently as the home port of a number of the largest cruise ships in the world. Southampton has a large shopping centre and retail park, Westquay. In 2014, the city council approved a neighbouring followup Westquay South which opened in 2016–2017.

In the 2001 census Southampton and Portsmouth were recorded as being parts of separate urban areas; however by the time of the 2011 census they had merged apolitically to become the sixth-largest built-up area in England with a population of 855,569. This built-up area is part of the metropolitan area known as South Hampshire, which is also known as Solent City, particularly in the media when discussing local governance organisational changes. With a population of over 1.5 million this makes the region one of the United Kingdom's most populous metropolitan areas.

Cork is a city in south-west Ireland, in the province of Munster, which had a population of 125,657 in 2016.

The city is on the River Lee which splits into two channels at the western end and divides the city centre into islands. They reconverge at the eastern end where the quays and docks along the river banks lead outwards towards Lough Mahon and Cork Harbour, one of the largest natural harbours in the world.

Expanded by Viking invaders around 915, the city's charter was granted by Prince John, as Lord of Ireland, in 1185. Cork city was once fully walled, and the remnants of the old medieval town centre can be found around South and North Main streets.

The third largest city on the island of Ireland, the city's cognomen of "the rebel city" originates in its support for the Yorkist cause in the Wars of the Roses. Corkonians often refer to the city as "the real capital", a reference to its opposition to the Anglo-Irish Treaty in the Irish Civil War.

Reykjavík is the capital and largest city of Iceland. It is located in southwestern Iceland, on the southern shore of Faxa Bay. Its latitude is 64°08' N, making it the world's northernmost capital of a sovereign state. With a population of around 123,300 (and over 216,940 in the Capital Region), it is the heart of Iceland's cultural, economic and governmental activity, and is a popular tourist destination.

Reykjavík is believed to be the location of the first permanent settlement in Iceland, which, according to Ingólfr Arnarson, was established in AD 874. Until the 19th century, there was no urban development in the city location. The city was founded in 1786 as an official trading town and grew steadily over the following decades, as it transformed into a regional and later national centre of commerce, population, and governmental activities. It is among the cleanest, greenest, and safest cities in the world.

Isafjörður, meaning ice fjord or fjord of ice, ice in plural genitive) is a town in the northwest of Iceland.

The oldest part of Ísafjörður with the town centre is located on a spit of sand, or eyri, in Skutulsfjörður, a fjord which meets the waters of the larger fjord Ísafjarðardjúp. With a population of about 2,600, Ísafjörður is the largest settlement in the peninsula of Vestfirðir (Westfjords) and the administration centre of the Ísafjarðarbær municipality, which includes – besides Ísafjörður – the nearby villages of Hnífsdalur, Flateyri, Suðureyri, and Þingeyri.

Akureyri is a town in northern Iceland. It is Iceland's Fifth largest municipality.

Nicknamed the Capital of North Iceland, Akureyri is an important port and fishing centre. The area where Akureyri is located was settled in the 9th century but did not receive a municipal charter until 1786. The town was the site of Alliedunits during World War II. Further growth occurred after the war as the Icelandic population increasingly moved to urban areas.

The area has a relatively mild climate because of geographical factors, and the town's ice-free harbour has played a significant role in its history.
