Planning your next vacation? Get more bang for your travel buck in these 10 world destinations.

These days who isn’t looking for good value? Keeping your budget and a craving for an unforgettable experience in mind, the experts at Lonely Planet have released their top picks for world destinations that just might satisfy both.

Top 10 best value destinations for 2012

1. Northeastern USA
The great cities of America’s northeast — New York, Boston and Washington DC — might not strike you as being a bargain, but Lonely Planet says you can save big by taking advantage of the recent boom in budget bus companies. These buses, which connect with the three major northeast hubs — and also with also places like Toronto, Philadelphia, and Pittsburgh — are a steal at about US$5 one way (and sometimes just US$1). Travellers can crisscross the region without the expense of booking a flight or renting a car. Plus the ride is touted as being comfortable and it offers free wi-fi. (Want to find out more?

2. Japan
Compared to popular destinations such as London, Paris or New York, the attractions and accommodations in Japan are relatively inexpensive. According to Lonely Planet, you can find simple, Japanese-style minshuku guesthouses from about US$37. Even better, many attractions such as temples and botanic gardens are free — and others are almost free. For example, admission to the Tokyo National Museum is a fifth of the cost of the Tower of London.

As we know, Japan has had a tough year with the earthquake back in March, and the country is considering various incentives to boost tourism in 2012, like possibly giving away thousands of free flights starting in April 2012. (See Japan offering 10,000 free flights for tourists… maybe.)

3. Tajikistan
Lonely Planet likes this Central Asian nation for its stunning scenery and stability – as well as its affordable rates. The cost for hiring a car and driver for several days, for instance, is about US$300, which can take you on one of the world’s greatest road trips up the Afghan border and Pamir Highway. For another great trek visit the emerald lakes close to the Uzbek border.

4. Porto, Portugal
This charming town with its atmospheric narrow lanes, historical trams, village-like plazas and buildings decorated with azuelo tile is also a good deal. Not only is it connected with much of Europe via budget airlines, but accommodation in antique-filled inns with river views start at just US$37.75. While you’re there, check out the traditional wine district of Alto Douro (which is a few hours east of Porto) where you can cruise in a flat-bottomed boat and sleep in 200-year-old homes for about US$86.
