How about getting some brain surgery . You are an idiot if you think you'll be able to afford to maintain the yacht and cars for more then 6 months . Only a dickless idiot would not invest the money . Of course you could still reward yourself whit a Ferrari or something while doing the investment .
You could provide investment for a company I'm starting and get a great ROI. Earn tens of millions of dollars a year minimum. By the way, this is a serious reply.
You could a buy your dream wife..Oopps not saying you would (With that much money, yea I probably would haha lol). Seriously, I think it is wise to invest your money, you could sleep and do nothing well your investment is increasing
Take half of that and make some long term investments. Use the second half to have a lot of decadent fun and help those around you, and you'll have the payoff from the long term investments to keep you alive comfortably.
Donate them and Try to Make Again 2 Million follow above step untill you get a idea that "what to do with 2 million $"
