Thanks for previous replies. All very helpful.
I called Amex Insurance this morning to ask if they have received everything. They just asked for proof of cancellation and proof of my flight to Split and proof my return.
Good news is they will pay for any loss from original departure time to when we boarded the cruise up to £300 per person.
However they say there is no cover for two days loss of our holiday. Any views on this?
Thank you again.
