Task-oriented dialogue about: hotel

I'm looking for a hotel to stay at in the centre, can you look this up for me?
There are three hotels in the center of town. Do you prefer something moderate or expensive?
Not in terms of that, but do they have free parking and have a 3 star rating?
The Gonville hotel has 3 stars and parking, and the University Arms hotel has 4 stars and parking. They are both expensive. Would you like more details?
Okay, I'd like to book a room at the Gonville Hotel for 4 nights. There will be 6 people and we will be arriving on Saturday.
I'm sorry, there are no rooms available for that length of stay. Could you shorten your stay or book a different day possibly?
Yes, what about 2 nights instead of 4?
Sure, that worked. You have booked 2 nights and your reference number is RU89U6V8 . Can I be of further help today?
No, that looks like everything. Thanks. Bye.
You're welcome. Enjoy your stay!
