Hi, I'm looking for a train going to Ely from Cambridge. 
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?
I need to leave on Wednesday after 12:00 please. 
TR1039 departs from Ely at 13:35, arriving in Cambridge by 13:52.  Does this work for you?
That sounds great. I would like to book it for 7 people. I will also need the reference number
Booking was successful, the total fee is 35.2 GBP payable at the station .Reference number is : JD1P380X.
Thank you I also need to find a cheap guesthouse to stay at. Can you help me find one?
You have 9 options available. Would you like to narrow it down by location?
The location doesn't matter, but I'd like it to be 4 stars.
Okay! How about Allenbell?
Sounds great, can you book it for 7 people for 4 nights starting saturday?
Your room has been booked. Your reference number is ELA3CIDM.
Thats all for today! Thanks so much!
Have a nice day.
