Speaker2: Have you ever been in Prague and/or be able to suggest places that we should visit there?
Speaker1: Nope and nope. But I could ask my sister, she travels a lot and probably already been there.
Speaker2: I know that the city center (old city) in general is a nice place.
Speaker2: But we have only two full days, so I'm trying to maximize the amount of sightseeing.
Speaker1: You should be able to find some info on the Internet - like guides to cities/things you need to see.
Speaker2: Well, we have guides, I'm just asking suggestions from people which have similar likes than me. :)
Speaker1: Cities are difficult to grasp when travelling, there's so many things and places to visit. Just go where the biggest crowd is and suffer ;)
Speaker2: Big crowds = full of pickpockets. :)
Speaker1: And full of people, I don't like crowds in general :P
