If not, I have later trains. Sentence4: I have 29 places to stay with free parking. Is there a price range you'd like to stay in? Sentence5: I want a train that goes to stansted airport and leaves from cambridge. Sentence6: I also need a hotel that has free parking. I don't need internet or anything like that.

Did you have a price range or area in mind? Sentence10: That train works well.
