U: How long is the travel time, and what is the price for that train please?

S: Sure, the travel time is 88 minutes, and the price is 13.28 pounds. Would you like to book it, if so how many riders will there be?

U: No that's OK, I'll book it later if I need to. Can you tell me anything about a lodging place named "A and B" something?

S: Sure. It's called a and b guesthouse, found on 124 tension road and is in the moderate price range.

U: Can you tell me if the guesthouse is considered to be quiet? I don't want much noise around me.
S: It appears to depend on what room you're in. Are you still interested or should I look for another option?
