thank you both for giving me food for thought. My party is DH and my 4 kids. I'm sorry for thinking "out loud" here but let's say I do cancel (only the cruise fare for discussion purposes). I have to send the X many credit card statements where I paid off the cruise. In addition, I have to send the invoices for each of the cabins where the total of the amounts paid should add up to the credit card statements. So in that case, it will be more difficult to separate each person to file claims on multiple insurance policies. So I'm back to thinking either insurance per cabin or just all together at the highest amount.
Hopefully, I never have to find out how any of this works but with our parents getting older and just spending so much more than I've ever spent on a trip, I think its worthwhile to try and wrap my head around it.
