Your booking on TR1772 was successful. The reference number is YV3K20RP. The total fee of 50.5 is payable at the station. 
Also looking for place to go in the west. I need the postcode, address and entrance fee.
There are a lot of great places to go in the west - museums, colleges, entertainment venues - what would you like to do?
Would you choose an entertainment venue for me? Museums and colleges seem so boring. I will need the address, postcode and entrance fee, please.
The only entertainment venues that I can find are colleges in the West. Is there another area you would like me to search?
Colleges are find, can you recommend one and give me the postcode, address and entrance fee?
I recommend Clare Hall. It is free admission, and the address is Herschel Road, CB39AL. 
That is great, thanks for your help.
You're welcome! Is there anything else I can help you with?
No, I think I have everything I need.
Thank you for calling. Have a great day and a fantastic trip to Cambridge. Goodbye.
