I would be leaving on Friday and i would be traveling to London Liverpool street and i would like to leave after 21:15 You could take the TR9557 at 21:59, or the TR3138 two hours later. I'll take the earlier train. could you tell me the travel time, and at what time I will be arriving at London Liverpool street? Sure, the travel time is 88 minutes and you will arrive at 23:27. Would you like me to book the train for you? That would be great, thanks. I am also looking for a hotel. I would prefer a 3 star hotel. I do not need parking. Certainly. I have many hotels matching that description. Do you have a preference for what area you stay in? I don't really care. Could you please find me a moderately priced one, though? I'd like a 3 star if possible. Excellent, we have 4 options, all 3-star and moderately priced. They only differ by location (north, south, west) and wifi availability. Do you have any preferences given this new information? I would really like a guesthouse. Is one of those a guesthouse? Yes, Alpha-milton guesthouse is a 3 star in the north in a moderate price range but no internet. Does this hotel interest you? Yes. Can I get the phone number and address please.
