Copenhagen is the capital and largest city of Denmark. This "friendly old girl of a town" is big enough to be a metropolis with shopping, culture and nightlife par excellence, yet still small enough to be intimate, safe and easy to navigate. Overlooking the Øresund strait with Sweden just minutes away, it is a cultural and geographic link between mainland Europe and Scandinavia. This is where old fairy tales blend with flashy new architecture and world-class design; where warm jazz mixes with cold electronica from Copenhagen's basements. You'll feel you've seen it all in a day, but could keep on discovering more for months. Copenhagen is considered a very liveable place because of its cleanliness. It’s considered as one of the very environmentally friendly cities because its harbour can be swum in and about a third of the city’s people use bicycles as their means of transportation. In their downtown area, the places to visit and to be entertained at are the Tivoli gardens and the Town Hall Square. If you want the very cultural and scenic areas the places to see are the Marble church, the Rosenborg castle, and the Christiansborg.

Belfast (meaning: "mouth of the sandbanks") is the capital and largest city of Northern Ireland, the second-largest city in Ireland after Dublin, and is situated around the River Lagan, which runs through the city. It is a port city known as the birthplace of the RMS Titanic, and for its political murals, documenting the ‘Troubles’ of the 20th century. Today, Belfast remains a centre for industry, as well as the arts, higher education, business, and law, and is the economic engine of Northern Ireland. The city suffered greatly during the period of conflict called "the Troubles", but latterly has undergone a sustained period of calm, free from the intense political violence of former years, and substantial economic and commercial growth. Additionally, Belfast city centre has undergone considerable expansion and regeneration in recent years, notably around Victoria Square.

Waterford is the oldest city in Ireland famous for its crystal ware and intriguing medieval history. Located on the River Suir, Waterford was once one of the most important European ports in times past. Today, Waterford still maintains its 'small Irish town' feel, and has a much more relaxed vibe than the larger cities, whilst still providing for most traveler's tastes. Appealing most, perhaps, to interests including history, culture, music and arts. Waterford, like most Irish towns, has a lot of pubs.
