I'm sorry,but we are fully booked on that date.
All of our rooms are fully occupied.
I'm afraid we only have a twin room available for the weekend.
Unfortunately, we're all booked up for May 10th,but I can let you have a room after May 10th.
Sorry,we're overbooked. But I can recommend another hotel near here.
We are very full just at present.
I'm sorry, but the hotel is full on that date.
I'm sorry,miss,we are full that week.
We can put you on our waiting list just in case we have a cancellation.
We would appreciate it very much if you could call us instead.
We're very sorry,sir,We hope you could understand us.
But we are fully booked for all types of rooms on that night.
I see,sir. We will do our best.
