Task-oriented dialogue about: train
hotel

I'm looking for a train that arrives in cambridge by 16:00.
I have a train from liverpool street arriving in Cambridge on Friday, it would arrive a little early at 15:07. Does this work for you?
No. I need a train that departs Bishops Stortford on Wednesday, please.
Alright I found five. When would you like to leave by?
Could I get the departure time for those trains?
Certainly, the departure times are 05:29, 07:29, 09:29, 11:29, 13:29
I would like the 11:29 train, please. I am also looking for a 4 star hotel.
I'm sorry, did you want me to book the train for you?
No I will take care of the train booking. I still need help finding an expensive 4 star hotel with free parking. I would prefer a guesthouse type.
I don't have any listings for expensive guesthouses. There are several 4 star that are moderately priced. Will that work?
Could you look for a cheap one?
I have 5 guesthouses in the centre, east and west. What area do you prefer?
I would like something in the center. Would you give me the name of the guesthouse, please?
The Alexander Bed and Breakfast is in the Centre.
Thank you for your help. That is all I needed.
I'm happy to help. Thanks for using our service. Goodbye.
