Allure 22nd-25th

Hey guys! I'm supposed to be cruising on Allure from Miami to the Bahamas the 22nd-25th of this month (leaves next Friday.) This is my first time on a cruise and with the potential for bad weather due to the storm that is forming, I'm just curious if anyone has ever had a cruise canceled and what that would look like in terms of refunds/rescheduling. I'm really hoping the storm heads north but trying to be realistic as well. Thanks!
