How hard is it and how much does it cost to change reservations. We were supposed to be in the World july 7 thu july 13 but there has been an emergency heart operation in my family. My "2nd Dad" is in critical condition but holding on. His condition changes from ok to bad constantly. I love him very much and cannot leave with him like this. I know I need to change the reservations 6 days prior to check-in so I have to make a decision by next Wednesday. If anyone has had to do this can you give me any idea what the cost will be? Thanks
