If I could, I’d move back to NYC, in a heartbeat. Or Paris.
Not in this lifetime, though.
We’re mulling a return to Honolulu once the wife retires (this year) and we can get things squared away here. That’s about our favorite place on Earth.
My needs are simple. The only thing I request is an exact replica of the Palace of Versailles on about 20,000 acres of land. However, it has to be an improvement on the original - I need central heat and air plus decent bathrooms. It also needs to be located in an area with a Mediterranean climate where people will not bother me. The land outside of the palace proper should contain an airstrip at least 10,000 feet long but not close enough to the palace itself so that noise pollution is not an issue. I want a world-class aviation museum on a corner of the grounds for the general public to enjoy (but for away from the palace itself). Other incidental details should include multiple shooting ranges, hunting grounds, off-road recreational vehicle trails and some of the best swimming pools, ponds and lakes in the world.
I am frugal so I don’t care a thing about yachts or wallpaper.
In fact it’s cold as Hell.
But . . . but . . . the pidgees!
Does no one like where they currently live 
I’ll stay where I am. High in the Colorado Rockies, no neighbors to speak of and my back property line touches National Forest.
In a hole in the ground. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat. A comfortable, well-appointed hole, with high-speed internet.
Like this one, say.
I have a friend who lives there. I visited her there once, it was beautiful.
I love the desert myself. When I retire I may move to New Mexico.
There’s a little town on the Sound in Washington that I love. I’m not going to name it because I don’t want everyone moving there and driving up the housing prices!
I’m hoping we can retire there. We’re native Californians, but I’ve always loved colder, wetter weather and hate deserts. And with the way things are going, I have a feeling that the current California drought is going to become the new norm and this state is going to become one big baked desert.
I’m happy to deal with rain and cold for the last couple of decades of my life. In fact, I wish I had moved there years and years ago.
I love where I live, too. Wouldn’t change a thing. I’m up in the Coast Range in western Oregon, live in a forest on a very private property, nearest neighbor a quarter mile away and we can’t see each other through my trees. I’m close to a nice-sized town and close enough to bigger cities when I want that sort of diversion. I’m surrounded by astonishing beauty, mountains, lakes and ocean are within an hour’s drive or less, great wineries, fabulous boutique breweries, food for the taking (berries, mushrooms, fish, game), abundant water… it suits me down to the ground. I feel so fortunate.
I nearly moved to the top of the South Island of New Zealand a decade ago (my husband was from there), and that would have been all right, too. If we’d been even 10 years younger, I’d have shaken the dust off my shoes and never looked back.
We’ll box 'em up and take 'em with us. 
But the move is still just an idea we’re just kicking around.
We like Bangkok just fine. After growing up in Texas, Hell itself would be a vast improvement. But just as Rick and Ilsa had Paris, the wife and I will always have Honolulu.
I love where I live, the Seattle area, but the population keeps going up and up and up. Half of California’s already moved here and our infrastructure CANNOT handle it.
Well, London is, I believe, the greatest city in the world, so a centrally located apartment there would be nice.
But there enough other places I’d like to live for a while as well. I’d love to do a spell in Hawaii. Cape Town sounds fascinating. Ditto Rio de Janeiro and Buenos Aires.
A nice part of Paris would be fun for a while, too. I’m assuming the “money is no object” part of the question means that I could afford immersion language courses, because I feel that in Paris particularly - moreso than for other countries where I don’t speak the language - I would be missing out a lot if I didn’t speak French.
