A lot of people look forward to their holidays, even if they like their jobs or schools. I like to be on holiday, because I can relax and change the rhythm of my life.

I like to go on holiday to other cities and countries. I like to see new places, new people. I like the sound of an unknown language all around me. I like the buzzing of an unfamiliar city. It inspires me and gives me new impressions. I feel free from everyday routine and my responsibilities.

I prefer a package tour when everything is organized for me. I don’t like camping or walking holiday, though a lot of my friends like to spend their free time in the countryside, far from the city.

I don’t like to travel by car. I would rather travel by train or fly by plane. I don’t like to have a big suitcase with me. I never take a lot of clothes. All I expect from my holiday is having a great time.
