As Carol says, each person’s circumstances will differ. We have an annual medical evacuation plan with Medjet Assist, to whom we switched after our last company stopped covering individuals.

Our medical insurance covers us world wide, but many do not, so verify that.

We own our home, so no cost there, but a boat charter can be expensive, so you may want to protect that investment.

Airfare is another thing. You can buy refundable tickets, or use miles that you can turn back in. If your nonrefundable tickets are cheap enough, then you can take the risk of losing them.
