Maybe we're weird; but we find that trip insurance is worth it for peace of mind. We've had one trip that was cancelled due to a kidney stone 3 days before the trip, and we were reimbursed in full. We had another trip where we were foolish enough to go despite an appendectomy a week before the cruise. We should have cancelled and used the insurance. Instead, I ended up in the emergency room in Barbados on my first day of the trip (the one we should have cancelled); so we still got our money's worth from the insurance.

If you need one medical evacuation, that will cost you far more than the cost of the trip.

We are extremely risk averse, and would rather pay for trip insurance than take the risk of a cancelled trip or the cost of a medical emergency while on the trip.

To us, "no insurance" is penny wise and pound foolish.
