U: I am planning a trip in Cambridge

S: I can help book a train to get you here.

U: Ok I will book it for you

S: How can I help you today? Are you needing train information or is there something else I can do for you?

U: I need an expensive place to stay that's 2 stars.

S: I show two hotels in the north, 1 is expensive and 1 is moderate. I also show 1 expensive 2 star hotel in the east. Which area do you prefer?

U: Do any of them have free parking?

S: express by holiday inn cambridge has free parking. That looks to be the only option available.

U: Do you know if Express by Holiday Inn Cambridge will give me a good value for my money?
S: Most of the guests that stayed there in the past have said it was overpriced. Would you like to find somewhere else?
