while i envy what you have saved , but ive been to to almost all thats listed. and i guess im halfway to retirement ( so youre the role model albeit i dont have your specialty) and should be making changes.

havent been to murica so i guess its a good idea to skip. and while youre driving autobahn to swiss even. i would recommend places like Czech or the other eastern europe. to me kinda worth the stop.

other notable mention like Vietnam island phu quoc.
id skip SK too.
