hotel

Hello, we are looking for information about lodgings in Cambridge. Price is no option and we would like a very nice hotel.
There are 33 hotels available, do you have any other criteria to narrow it down?
As long as its insanely expensive and has free parking. Centre located please.
I would recommend the university arms hotel. It is in the centre, expensive, and has free parking. Can I help with anything else?
I want to book it for 5 people for 2 nights starting on thursday.
Okay, you are all set! Reference number is : RGBB7MTN .
Thank you! I'm also looking for a train departing from cambridge that leaves on saturday.
What is your destination please and travel time?
I'm heading to Broxbourne, and I need to arrive by 11:15.
TR0823 will have you arriving at 11:01. How many tickets do you need?
I am not sure how many yet. For now, I need the departure time and the length of travel time for TR0823.
The departure time is 10:01 and the duration is 60 minutes.
Ok, that's all I need for now. Thanks, bye.
Okay, have a good day.
