Make sure you have really bulletproof insurance. I know of a guy that went to Germany (from Australia) to go to one of these special clinics. He died over there, and the family had to pay for the repatriation of his body (which is eye-wateringly expensive). Wiped a huge chunk off his estate, and that wasn't able to be liquidated until well after his repatriation, which meant having to borrow money. If something happens, you will want to be covered.
