That one sounds easy to handle on your own, @Tisha34 . You won't have to wait on hold for hours.
Just cancel. Your check-in is between Mar 14 and Apr 14, and you booked before Mar 14, so the system should generate a full refund.
You will probably get some prompts. My guest who was supposed to come tomorrow hit the cancel button, and the system prompted her to go through some steps to be fully refunded. She was nice enough to add an explanation to the system-generated message that said "I have cancelled due to the incident affecting [my town name]." I really appreciated her personal note.
Unless you chose that "nonrefundable" lower price that some listings offer when you booked, you should be good. Will you write to say how it goes?
