Hi all Im off to Prague in a few weeks and I wanted a little advice on a number of things: 1. What currency should I take? I understand they dont use officially Euros, so I will need local currency (Koruna). I guess I should take Euros too, but will US dollars also be useful? 2. Can anyone recommend a guide book (which hopefully would include some basic czech phrases)? 3. Any other tips for visitng Prague? Thanks in advance.
