Hello how may I help you? can you help me with some information please? Yes I can provide with information about different cities. Okay, I need to know what river goes through Prague? That would be the Vltava Wow, that's great. Do you know if there are river boats tours? There are river boat tours that depart every day of the week during the summer season. Perfect. This is exactly what I was looking for Is there anything else you need? That's all. Thank you so much for your help You're welcome.
