Yes I am looking for information on a hotel called City Center North B and B.
I cannot find that hotel. Any other hotels you would like to find? 
Could you check the spelling(city centre north b and b) and try to search again?

I am also looking for a train into Cambridge from London Kings Cross. 
there are many trains but you need to tell us which day you want to travel
I will be traveling on Thursday. 
Do you have a time preference?
I need to arrive by 14:15.
The first train leaves at 5:17.
Well that will not work.
The TR2512 will fit your needs. Would you like to book this train?
Not at this time. What is the travel time for that train, please?
The TR2512 takes 51 minutes. Anything else you need?
no that will be all thanks
