I’d love to spend some time living in a serviced apartment with meals included.

Or something similar to a retirement village or university student accommodation, or be able to afford a staff of servants. You get the idea anyway.

Imagine if jail fit that description.

you'd be surprised how far 600/month goes in south america

Just being retired is good enough for me.

You can do this quite affordably in huge numbers of countries if you can earn your income with a decent remote job in the US. The things to think about are time zone, tropical disease, quality of food, and safety. There are a whole range of places from Arkansas, to Costa Rica, to Panama, to Nicaragua.

The thing you'll lose out on is anyone you know, unless you can get them to go with you, or can make new friends in your destination.

I’m in Australia so I often half-joke: let’s sell everything we own and go live like kings on a remote Indonesian island.

Yes that's really the best part. School 5 hrs a day and then free time !
