Places I've loved:
China
Italy
Nicaragua
Lao
New Zealand
(yes I know they aren't similar)
Places I've hated:
LA
(That's it, literally nowhere else. Just LA. It's awful.)
I want to go somewhere with my elderly but adventurous mother (can't carry a back pack but still much fitter than me) and my DBro. It's probably a last hurrah in some ways. Last chance to indulge a shared love of slightly shitty, minorly scary travel.
Mum doesn't want anywhere with really shit food, beds as hard as China or too touristy. DBro needs culture, architecture, likes people who don't engage too much (he's very much high-functioning spectrum). Me, I need adventure, weather that is neither too sweltering nor too cold (24-27 degrees is perfect!), interesting people who aren't too focused on tourists (so China good, Thailand bad).
Suggestions so far, ranged from maybe to hell no:
Patagonia
Mongolia (I want to save it for the TransSiberian with DH one day)
Montenegro
Albania
Sichuan
Tibet (already been sort of)
Uzbekistan
Iran (Southern, not the scary bits)
Pakistan (fancy it but you know)
