I need some information on a train going to cambridge.
I'd love to help you with that! What day are you headed out?
Sunday. Sometime after 21:00, if possible.
There are multiple trains headed to cambridge sunday after 21:00. Where are you leaving from?
I am leaving from ely.
I have train TR4205 that leaves at 21:35 and will arrive in Cambridge at 21:52. The price per ticket is 3.52 pounds. Would you like a ticket for this train?
yeah, i need eight tickets.
Booking was successful, the total fee is 28.16 GBP payable at the station, your reference number is  0V72HM78. Will that be all?
I also need a guesthouse located in the north.
There are several choices, but all are priced either cheap or moderate. Which would you prefer?
Are there any with a star of 4? I'd like free parking as well if that is available.
I have 7 entries that fit your criteria. 6 are moderately priced, and one is cheap. Would you like information about any of these?
