I've got a trip planned for October LAS-MLE then 10 days split at two Maldives resorts before flying MLE-LHR, 5 days in London then LHR-JFK. All of this is contingent upon:

A: The Maldives allowing split stays between the two resorts I have booked.

B. The UK allowing vaccinated Americans to enter from the Maldives.

Can I buy an insurance policy that will reimburse me for the last minute expenses I might incur should either of those not be allowed???
