Travellers want to go green and stay clean in the next year -- and they don't want cell phones disturbing their peace, according to an annual survey of travel trends.

TripAdvisor, a travel Web site, surveyed more than 2,500 travelers globally, finding the top trends were concerns about germs, the growth of green tourism, and opposition to cell phone use on planes.

It also found emerging hotspots for vacations in 2008 were Jerba in Tunisia, Makandi Bay in Egypt and Phangnga in Thailand.

'The major trends we're observing are that travelers value cleanliness above all else and are becoming more environmentally conscious,' Michele Perry, spokeswoman for TripAdvisor, said in a statement.

The survey found 80 per cent of respondents were concerned about germs, bacteria and viruses when traveling.

Aeroplanes were deemed the most germy, according to 28 per cent of those polled, with public transportation next, followed by restaurants, hotels, and airports.

In keeping with the germaphobia, 55 per cent of travelers said they tend to wash and disinfect their hands more often while traveling with 27 per cent of Americans -- up from 22 per cent in 2005 -- taking disinfectant, cleaning supplies, shower shoes, pillows, towels or linens, when going on a trip.

Nearly half -- or 45 per cent -- of travellers said their worst experience at a hotel was a dirty bathroom or dirty sheets but 17 per cent said they encountered vermin.

Travellers are going greener, with 26 per cent planning to be more environmentally conscious in their travel decisions in the coming year, with plans ranging from biking to hiking.

They clearly don't want cell phones disturbing their peace, with 78 per cent of travelers believing that mobile phones should not be allowed on flights.

The survey found that 53 per cent of travelers said it takes less than a day to unwind on vacation while 35 per cent take 1-2 days to relax.

Travellers will average about three vacations in the coming year with beaches getting hotter as 64 per cent plan to vacation at a sandy spot this year, compared to 59 per cent last year.

Using a system that looks at various criteria such as search activity and postings, TripAdvisor predicts the rising stars in travel.

It said the top three emerging world hotspots for travel are Jerba, Tunisia, Makandi Bay, Egypt and Phangnga, Thailand.

Rounding out the top 10 are Kovalam in India, Sabaudai in Italy, Asilah in Morocco, Ko Phangan in Thailand, La Plagne in France, Yangshuo in China, and Kotor, Montenegro. Reuters
