As you see in below, we have booked 2 rooms for Feb. 4 night, and I am just emailing you for confirmation.
And, because 2 of our friends have changed their plan, they would go to Pai later. So, we would like to cancel one room. Is this still possible without charge?
Means that we want to keep one room for Zhan and Chen. If possible, and without charge, we want to cancel another room.
