Travel / Night Travel Warsaw-Prague [5]

Dear Friends,

I need your suggestions/help.

I am planning to travel form Warsaw - Prague on 3 Nov night.

Being a student, looking for the cheapest "Budget travel" option.

(Please don't post/answer something like Walk..)

I looked for Eurolines Bus & it is about (931 czk)

For this Should i Book in advance or can i buy few hours before the departure ?

ELSE..................

I heard that If I follow the following steps it can be still cheap (But RISKY ????? !!!!!!!).

But don't know how exactly it works ...i mean which type of train... etc etc,..( I don't speak either Czech or Polish..can manage a bit with English)

STEP 1

First, Buying a ticket in Train (?) from Warszawa to Zebrzydowice

STEP 2

Then a special train ticket in train (?) across the border from Zebrzydowice to Petrovice

STEP 3

Finally, Buying a ticket In train (?) until the Petrovice to Prague.

Can anyone tell me how much it costs ???

If I catch/take a direct train (sleeping/seat couch..something like that ...) how much it costs??

(I don't have any rail pass...)

Else is there any other cheap means of transport ?

If anyone can suggest/ help in this regard I would be Grateful & Thankful to you all...

Best wishes

Warm regards!

Sravani !
