Have never purchased trip insurance for our cruises, but am thinking that it might be a good idea.
Is it "worth it" for individuals. Depends upon your situation. Can you afford not being able to complete your trip and get pay to be evacuated back home? Family of 4 on a 7 night cruise may spend 6,000 for their cruse and to be evacutated back to the US may cost them another 5,000. So is the "$200 gamble" worth covering $11,000 in real, out of pocket expenses? It's sounding better to me all of the time.
Lets tackle the issue of the "big bad insurance company"
I'll work on the math making some very huge assumptions (because I really don't know the frequency of insurance claims nor the cost of the insurance. I do know that most insurance companies have to have losses under 65% of the premiums collected to break even).
2000 people on the ship and lets assume 40% of the people have trip insurance and if the insurance costs $50 per person. So the insurance company collects about $40,000 per week. Break even = $26,500 in claims. If the frequence of medical evacuations occur once every other week and may cost 25,000 (12,500 per week average) that leaves $14,000 per week to cover accidents / illness before leaving home and other "minor" incidents during the cruise (like the norwalk outbreaks). 14,000 really only covers about 4 families per week. So I don't think that the insurance companies are "ripping us off".
