In today’s world, so many people like traveling around the world. Traveling abroad can be expensive, but there are some ways of visiting Britain cheaply. So we hope  we can give you some good ideas.

If you don’t go there in the busy months—July and August, your visit may be cheaper. There will be fewer visitors. The weather in Britain can be pleasant from April to the end of September. Of course  you can go there in winter, but it is often dark by 4 pm. Many places, such as large houses and castles(城堡)are closed in winter. However, if you are interested in museums, art galleries(画廊) or theaters, winter may be the good time to visit.

If you are a student, it is a good idea to apply for (申请) an International Student Identify Card. With the card, you can save a lot of money. You can get the card from your local (当地的)student travel office, and you can also call (44)08708 413224 to get it. To get the card, you need to show that you are a student, get a passport photo, and pay for a little money.
