There are 70 trains do you have a date and time you'd like to go? TR4212 is arriving at 9:52 would that work for you? The train leaves at 9:35. Shall I book it for you? Of course, there are many 4 star hotels to choose from. Would you like me to book one for you? There are 18 guesthouses to choose from, do you have a preference to the area you would like to stay?
I am looking for a train from ely to cambridge. Do you have such trains? I would like to leave on a sunday and arrive by 11:30. What time does that train depart? No, thank you. I would like to see if you could find a place for me to stay that would have a 4 star rating. Not yet, thanks. Are any of them guesthouses? I need a 4 star, and in the east with free wifi for 4 people, 5 nights. I'll need a reference number.

Do you want that guesthouse reservation to begin on Sunday?
