I was in Praha about five years ago and had planned a bus trip there, I believe it is about a 2-3 hour ride. I got cold feet at the last minute and bailed on it, I was worried about making a mistake (missing the stop, getting on a wrong bus, etc.) and I needed to get back to Praha for an important evening concert. I don't regret it too much, there is only a Mahler house to visit and not much else. BTW, I listen to a station called Classic Praha on the internet, that's why I use Praha.
