Dear Roy,
Thank you for your letter. I was glad to get it.
As for me, I prefer to travel by plane. In my opinion it's the fastest and most comfortable way of travelling. Though it's too bad, it's not the cheapest.
Yes, I like to stay in hotels. I consider it to be a good option. But I also have nothing against hostels. They really have all the necessary things and are much cheaper than hotels.
You ask me about my friends abroad, well, I got acquainted over the Internet with a girl from Poland, and we are now pen-friends. What about you? Do you have friends in other countries?
Now I'm finishing. Write soon.
Best wishes,
Alex
