Task-oriented dialogue about: train
hotel

I am looking for a hotel to stay in with a 4 star rating that is in a guesthouse style.
I like acorn guest house. Need me to book a room?
Does that include free wifi?
They do indeed provide complimentary Internet access. Would you like to make a reservation?
Just one more question: Is it in the moderate prince range? If so, please give me their address. If not, I need something moderately priced.
Yes, it is. It's located on 154 chesterton road, cb41da. Would you like a room?
No thanks. Not at this time. I would appreciate some help finding a train to get me to Ely though.
Can you tell me where you will be leaving from and on what day and time?
I would like to leave after 15:15 on Thursday.
We have a train departing Cambridge at 15:50, arriving at Ely at 16:07. Would you like me to book a reservation?
Yes that works great. Can you book 2 tickets for that train and give me the reference number?
Your booking was successful. The total fee is 8.8 GBP payable at the station. Your reference number is H0BMD920 .
Great. That's all I needed. Thank you.
Have a nice day, goodbye!
