I am hoping that your hotel will give some of it back. Your reason is not an emergency and it depends on the date that you booked and the date of your expected stay. My hotel offered this, but it was better for me to just go there. If the hotel says no, I found a site called Transfer travel.com. You can sell your room online, minus a 15% fee. They stated that 80% of hotels let you change the guests name. Read the hotel cancelation policy. Just an option.
