Tourism is travel for pleasure; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. This act may be done internationally or within the country. Tourism can be domestic or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Today, tourism is a major source of income for many countries, and affects the economy of both the source and host countries, in some cases being of vital importance.
After Doomsday, the tourism industry came to a standstill from the 1980s to the early 2000s. From that time, the surviving states of the world resumed contact, the global economy began to rebuild, and security started to return to many regions; these factors have led to a revival of tourism, though it has certainly not reached prewar levels.
Around the world, there were millions of tourists visiting the famous landmarks and vacation spots. In the United States alone, the famous tourist cities included New York City, Washington D.C., Miami, Los Angeles, San Francisco, Seattle, Chicago, Denver, Houston, Dallas, St. Louis, and Las Vegas. These cities were famous for their iconic landmarks that defined American culture (freedom, liberty, capitalism, money, technology, amusement parks, etc.) and hence were flocked by millions of tourists annually. Across the Atlantic Ocean, the famous tourist cities was in London, England; Rome, Italy; and Paris, France, which was famous for its rich history and iconic landmarks such as the Big Ben, Buckingham Palace, Vatican, Colosseum and Eiffel Tower. In other parts of the world, tourists mainly visited the famous beaches along islands in the Caribbean, the Pacific, and parts of the Indian Ocean. Some tourists chose to go on a nature trip to the jungles of South America and to the safaris of Africa.
The weekend of September 25-26, 1983, would change the tourism industry forever. Most of the world's famous cities were destroyed in the nuclear war, wiping out iconic landmarks and billions of people, including tourists. In areas not affected by the nuclear fire, foreign tourists were stranded, seemingly forever. This was seen in the Caribbean islands where majority of the American, Canadian, British, French and other tourists had to indefinitely stay where they were after losing contact with their homelands. In Europe, most of the best locations for tourists was destroyed, except for a few cities such Dublin, Berlin, Venice, Florence, Genoa, Helsinki, Zurich, Palermo and some minor sites. In some cases, things turned ugly when tourists incited riots in the country, particularly in Egypt when majority of the Western tourists stormed embassies of communist countries. Tourists in South America, Africa, Asia, and in Australia had the same experience. It would then appear as if the areas they were stranded in would be their new permanent home.
From that fateful day in September 1983 to the early 2000s, the majority of the world's tourists were still stranded in where they were. The weeks following Doomsday and tourists would receive shocking news from refugees brought about by ships, freighters, and ferries. It would take more than a decade to get in contact so others have finally come to accept that their homeland was ultimately destroyed and began to live their lives in their new homes. In some cases, many tourists chose to live in other nearby countries not affected by Doomsday. When the USS Benjamin Franklin and the USS Nimitz led an expedition around the world, there they were able to get in contact with some stranded tourists abroad.
In the case of the American diaspora, they were offered to resettle in the Commonwealth of Australia and New Zealand and its associated territories. While many chose to go to rest of the American community in Australia or in the United States Atlantic Remnant, other tourists who had already adapted to their new home opted to stay, such as in the Philippines, Korea, Japan, the Bahamas, Jamaica, Netherlands Antilles, Puerto Rico, and among the numerous surviving states in the world.
With contact and travel restored in some parts of the world, the tourism industry has been revived and is currently on the rise. However, there are limits to this industry as there are still parts of the world that have a significant amount of radiation left over from Doomsday. The safest locations for the tourists are South America, Asia, Oceania and some parts of Europe. Tourism in North America plays a role in the economies of Canada, Florida, Mexico, Superior and Niagara Falls. Mount Rushmore in particular is a popular site for tourists visiting the former United States and a place of pilgrimage for the American diaspora since it survived unscathed after Doomsday. The islands of the East Caribbean Federation are safe and have sought to promote tourism, but growth has been slow due to the much reduced economies of North America and Europe. In the Italian nations of Tuscany and Venice, tourism has become a key pillar of the economy. Tourism is an important economical sector throughout Italy, though only a minor sector in Sicily.
In Asia, famous tourist spots include the Philippines, Jeju Island in Korea, Hainan, Macau, Taiwan, some parts of Indonesia, and the Maldives. In Oceania, the Commonwealth of Australia and New Zealand has taken the role of the former United States that attracts lots of tourists. For Australia, tourists are treated with pristine beaches to the West and the Outback in the interior of the island. In New Zealand, the mountainous terrain provides an environment similar to the Swiss Alps in the Alpine Confederation. The islands around the Commonwealth, of which the Federated States of Micronesia and Samoa are an integral territory, as well as the islands of Belau, Vanuatu, Tonga, Tokelau, Nauru, Papua New Guinea, Kiribati, among others are known for their white-sand beaches and virgin forests.
In some parts where Doomsday took its tall, there are some areas prohibited to enter due to radiation levels and warlords fighting for territory. An example of this is Mainland China, where warlords and differing factions have been fighting for control over the mainland.
Other reasons may include hostile environment, unexplored areas that may pose a significant danger, and civil war. Travel in some countries in Africa and some parts of Latin America is highly discouraged due to these reasons.
