One thing I noticed with the GeoBlue plans is that the maximum medical coverage drops to $100,000 from $1,000,000 at age 70. Is that enough? Wouldn't want to find out the hard way that it wasn't.
I've been purchasing single trip coverage (from Trip Insurance Store) for less than the total cost of the trip. It seems that the lowest premium is for coverage at $500. I'm more interested in having higher amounts of medical and evacuation coverage than getting reimbursed for the cost of the trip.
