     One of the main decisions you must make when traveling is deciding where to stay. A good place to

stay can often make a holiday. Whether you are looking for a classy hotel or a night under the stars, we

can guide you through your different options.

     Bed and Breakfast

     An English invention, bed and breakfasts offer exactly what they suggest, a bed for the night and

breakfast in the morning. People who hate the anonymity of hotels but want more luxury than a hostel

often choose to stay at bed and breakfasts. "B&B's", usually someone's private home, are often found

in the countryside.

     Hostels

     For those traveling on a tight budget, hostels are the best accommodation option. Informal places

usually with a friendly youthful vibe(氛围), they offer dormitory beds for rent. Bathrooms are usually

down the hall.

     Remember to check reviews by previous guests online before you book your hostel.

     Couch Surfing

     An unusual but interesting option, couch surfing is a growing trend among young internationals. The

idea is that you become a member of the online couch-surfing community (www. couchsurfing. com)

and then when you travel, look up other members in that country and ask to stay on their couch (沙发).

Most hosts will suggest sightseeing trips and take you out in the evening, making it a great way to see

things that aren't in your guidebook. And remember, it may be free but don't forget to offer to buy your

host a drink or dinner.

     Camping

     Sleeping under the stars! For budget travelers staying at camping grounds is the cheapest way to

travel. The drawback is that you have to carry a tent with you. Camping grounds can be found across

Europe, America and Australia. However, if you intend on camping in busy cities, check first where the

nearest campsite is. More often than not, they are on the outskirts, which can mean lengthy bus rides into

town when you want to eat or see the sights.
