Hello 140KIAS,
Sorry for the delay in giving you an answer but I have been waiting for a definitive answer to your question.
Unfortunately I still have not received a detailed answer due to Eveline being away, but I was told in a quick (Blackberry Style) Email, we refund as much as we can.
Once I get a definitive answer I will post it.

Book now to avoid disappointment!
Further updates later..
