Well, obviously there were areas of the world that contains the EF, Arendelle, Agrabah, etc, that are outside the bounds of the curse. Otherwise, Hook would not have been able to outrun the curse. Ariel and Eric were not touched by the second curse, either.

So, I think it is quite possible that the Curse does not affect Arendelle or the other kingdoms the same way as it affects the EF. Though it is possible that those kingdoms were "frozen" in time for the first (28 year) curse. (kinda like Sherwood forest, since Robin and company missed the first curse, but otherwise did not age during the time). But I don't think Snow's curse had that effect, since everyone was aware of the curse and passing of time in Storybrooke, they just forgot the 1 intervening year.
