I believe it's implied Arendelle only unfroze after Ingrid had to use a lot of magic to cast the spell of shattered sight, which caused the kingdom to unfreeze. This actually was confirmed by Adam on Twitter.

As for Wonderland and Victorian England being frozen, it's because everything that was untouched by the Curse was frozen by it (look at 2A Misthaven), in that sense, the Dark Curse did reach into all the lands.
