I don't want to pay for a hotel room that I won't be staying in
Why would you not pay for it?
I'm not using it, so why should I pay?
If you won't use it, you shouldn't pay for it. It's only right.
That is what I'm going to do. Then me and my friends will be able to celebrate our birthdays together with all the money we saved!
I hope you have a good birthday. I am glad that you will have money to spend on your birthday since you won't be spending on something that you are not going to use.
