I think the history of the 20th Century has quite a few examples of situations where society broke down to a large extent within certain regions and yet it was possible to survive (in a world which overall was progressing technologically) for long enough to relocate somewhere safer. Survival in those situations probably depends on luck to quite an extent but survivalist type preparations would likely have increased the chance of survival. The US (where cryonics seems to be most popular) did not really suffer any such situations in the 20th century, with the possible exception of a few natural disasters, but much of Europe and Asia did.
I think the main area where I differ from most cryonics advocates on the probability of it working is in the likelihood of the cryonics institution surviving intact until revival is possible. I think in a future scenario somewhat like WWII in Europe or the cultural revolution in China a cryonics institution would be unlikely to survive but human civilization would as would lucky and/or prepared individuals.
