I can help you with that. Can you confirm if your destination is Cambridge and any time preference you have?
Yes, my destination is Cambridge and I need to leave after 19:30.
I show 4 possible options.  Is there a particular time you would like to arrive by?
It doesn't matter. I just need tickets for four people.
I have booked you 4 tickets on train TR3873. It will depart at 20:24 and will arrive by 20:52. Your reference number is CBFDX67S. Anything else I can help with?
Yeah, I'm also looking for a place to go, perhaps an attraction in the east. 
There are a few attractions located in the east.  What type of attraction are you looking for? There are museums, boats, sports, parks, and etc.
Whichever is your favorite would be fine.
I would recommend the cambridge museum of technology.
What type of attraction is that?
It is located at the old pumping station, cheddars lane. The cost of admission is 5 pounds
Is it a specific type of attraction?
It's a museum. Is there anything else I can help you with?
