Inter rail: How much would it be a bed supplement in 2nd class night trains in eastern Europe?(approx.)?

Im going this summer around Europe and I want to see how much money i need. As I cannot find this information, I wanted to ask you please if you know how much it costs to pay the bed train supplement in eastern european countries (jut to have an idea).

thanks!

Why dont you try phoning the company you want to book it through, I am sure they will give you the accurate answer rather than yahoo answers....

I'm sure it will depend entirely on which country you are in. The easiest way to find out would be to google the railway companies of the countries you are interested in travelling in. Alternatively, this site is very helpful for rail travel in Europe:- http://www.seat61.com/

This particular page actually gives you photographs of the types of berths available:- http://www.seat61.com/citynightline.htm
