Business people often have to travel a lot. If you spend a lot of time traveling through Europe, you probably stay in hotels there frequently.
Cheaperthanhotels.co.uk is a website that will help you find inexpensive hotels in Europe. Even if you do not ever travel to Europe, I want to post this site as an example of an internet business. This site offers a useful service and as such they probably make a good amount of traffic and revenue.
They offer information about London Hotels. Staying in London offers the advantage of the English language. You will find it easier to stay in a country with the same language as you.
They also offer information about Paris Hotels. Paris seems like the most popular European destination for tourists to me.
Also, they offer information about Berlin Hotels. Berlin is in Germany. Germany has a sour but interesting history. If you go to Germany, you will probably stay in a hotel in Berlin.
If you travel to Spain, you will probably want the information about Barcelona Hotels. Many people like to travel to Spain, but you may also have to go there on business. It would be easier if you speak Spanish, but it can be fun regardless.
I imagine it is getting more expensive for people who use the US dollar to pay for hotels in Europe, because the dollar has fallen greatly in relation to the Euro. Luckily, you can find a wide variety of prices. Don’t spend out of your means.
