First of all, I would assume that Jason had a credit card...most people do, especially businessmen. I could outfit a home tommorrow with my credit card. No need to wire money. My husband worked for an International company and our credit card did not charge us transaction fees. If you travel frequently, and have excellent credit, those cards are available. Jason had the wherewithal to pay cash for an expensive home. His credit was undoubtly excellent.
Our children have been married in expensive American weddings....one with 300 attending with sit down rehearsal dinner catered in the Tiffany glass room at the Chrysler Museum in Norfolf, Va...a hotel reception the next day with orchestra and flowers, etc plus gift bags in out of town guests. I mention this because I have direct experience with the costs. And the American customs.
It is NOT the custom to buy the bridesmaids attire...to spend $50,000 or $80,000 indicates to me that Jason the Generous was somehow convinced to pay everything and the Martens paid nothing. It is NOT the custom to pay for guests hotel rooms.
I would love to know why the pictures on MM's FB now and before...seem to show that the Marten Family entourage was carted along on every cruise. Jason was known for his generosity. Maybe the loss of the Martens family Cash Cow enters into the motive.
