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?
I'm looking for a train. The train should arrive by 16:00 and should leave on saturday.
