If you call II you can find out if you purchased insurance - I always buy it for the fall in case of hurricanes, but II has never sent me the form which they say is automatically sent. However, they do have the records...as it's not a loss for them, but for the insurance company they work with "Insure America".
I had to cancel a week for labour day week this year and had it insured - not for hurricanes but for a health reason, so I'm in the midst of getting their many forms completed and getting the doctor to fill out the required forms and provide his notes back to 60 days prior to booking the insurance, results of diagnostic tests, etc. - quite detailed in fact and don't think the doc was too pleased. Supposedly, according to II, I'm covered for up to $1000 which will be based on 80% of the rack rate for a 2 bdrm suite at Manor Club for that week. A good test of the II insurance however, and we'll see what they finally cover and whether it's worthwhile buying it in the future.
I don't know if you can get coverage for bonus weeks, but suspect you can as no doubt II gets a commission on all the insurance they sell...but it's probably too late now if you didn't buy when you got the exchange.
