The World Tourism Organization (UNWTO) forecasts that international tourism will continue growing at the average annual rate of 4 %. By 2020 Europe will remain the most popular destination, but its share will drop from 60 % in 1995 to 46 %. Long-haul will grow slightly faster than intraregional travel and by 2020 its share will increase from 18 % in 1995 to 24 %.

With the advent of e-commerce, tourism products have become one of the most traded items on the internet. Tourism products and services have been made available through intermediaries, although tourism providers can sell their services directly. This has put pressure on intermediaries from both on-line and traditional shops.

Space tourism is expected to "take off" in the first quarter of the 21st century, although compared with traditional destinations the number of tourists in orbit will remain low until technologies such as a space elevator make space travel cheap.

Technological improvement is likely to make possible air-ship hotels, based either on solar-powered airplanes or large dirigibles. Underwater hotels, such as Hydropolis, expected to open in Dubai in 2006, will be built. On the ocean tourists will be welcomed by ever larger cruise ships and perhaps floating cities.

Some futurists expect that movable hotel "pods" will be created that could be temporarily erected anywhere on the planet, where building a permanent resort would be unacceptable politically, economically or environmentally.
