My SIL is sailing on Celebrity Infinity July 13 out of Venice with a party of 6 for their 70 Birthdays. Due to medical reason one couple has to cancel. At the time they booked three months ago, there was a small medical problem that time would take care. But now a surgical procedure has to be done next week with 3-4 weeks of rest. Did not get insurance, celebrity wont refund, or credit for a later cruise, etc. This trip was about $10,000 per couple. Airfare, hotel and cruise with a few extra days in Rome. Any help of where to start.
