I need a moderately priced 4 star hotel.
I have many guesthouses that meet that criteria. Do you have a certain area in mind?
I will need free wifi and parking.
Acorn guest house has that, will that work for you?
book it for 7 people and 3 nights starting from sunday.
The reference number is,VAKDVQNB is there anything else I can do for you?
I also need train tickets.
Okay, please tell where you are going and where you are leaving from, and what day.
I am going to Kings lynn from Cambridge. I leave Wednesday. 
What time would you like to travel? There are trains every hour from 5:11. It takes 47 minutes to get there from Cambridge.
I'd like to arrive by 17:30. Any trains that do that will be fine. I just need the price. 
TR8890 arrives at 16:58. It costs 9.80 pounds. 
Thanks for the service, goodbye.
I'm happy to be of service! Thanks for using the Cambridge TownInfo centre.
