I don't because we book room-only reservations and not packages, which has a better cancellation policy. With room-only, you can cancel up to five days out with no penalty and under that with only losing the first night's deposit. Since packages have a stricter cancellation, I would probably consider it if I went that route, since you have to cancel 46 days in advance. With five days out, if someone is already ill or whatever, I can go ahead and cancel. And with less than that, I would still only lose a one-night deposit--not too bad. When we cruised, we bought the insurance since you had to pay so far in advance with their cancellation.
