My choice, is a few planes, and probably another motorcycle. I'd probably buy a plane that could handle a more varied load than a business jet and still get you there at a reasonable speed, and then something for fun. A mild aerobatic plane as opposed to the serious competition ones. If I had some cash left I'd go for a T-34 or T-28. If it was 10 million I might try and find a WWII Corsair, but that would probably burn through the 10 million in a few years.
That's just me, I'm not a boat person, but I get some love boating.
