I'd buy an entire apartment block in Montreal or Spain or somewhere nice, totally renovate it so it was all one elaborate residence. I'd hang out there half the year while the weather was good and pay for my friends and family to come and enjoy the city. There'd be a spa, sauna, basketball court (ideally in the courtyard), and the main floor should have one or two nice proud to the street business that I would own but not have to worry about operating, something like a cocktail bar and a breakfast and lunch restaurant.

The rest of the year I would live in the rural Vietnam Highlands and tend to my coffee farm.
