S: There are 70 possible trips. You can leave as early as 5:35 and as late as 23:35. The trip is 17 minutes. What time of day would you prefer?

U: I need to leave on Wednesday after 12:00 please.

S: TR1039 departs from Ely at 13:35, arriving in Cambridge by 13:52.  Does this work for you?

U: That sounds great. I would like to book it for 7 people. I will also need the reference number

S: Booking was successful, the total fee is 35.2 GBP payable at the station .Reference number is : JD1P380X.

U: Thank you I also need to find a cheap guesthouse to stay at. Can you help me find one?

S: You have 9 options available. Would you like to narrow it down by location?

U: The location doesn't matter, but I'd like it to be 4 stars.

S: Okay! How about Allenbell?

U: Does it mention having strong water pressure?
S: I just read a review complaining about the low water pressure at Allenbell. Would you like to hear about other lodging options?
