The Prime plan allows you to insure a higher trip cost than the Essential plan and also includes higher amounts of coverage to protect your pre-paid non-refundable monetary investment. This plan includes benefits for missed connections and changes in itineraries, along with a pre-existing condition waiver.
To learn more, see the Nationwide Prime product page.
However, you did purchase the optional "Cancel for Any Reason" coverage which reimburses you if you cancel your trip for "other than a covered reason".
As you stated, travelers should always take time to review the policy terms and conditions. None of the plans on our website offer Cancel for Any Reason at 100 per cent reimbursement. We welcome you to call Customer Care at (800) 487-4722 for assistance when quoting or purchasing a policy.
