I have no idea of what Rebbe Nachman desired, except for his known wish to be buried in Uman.
Since we do have some record of that wish, it would be presumptuous of me to suggest anything contrary
to it. Of course, I have no personal stake in the matter, since I am not A Breslover. Personally, suspect that Josh31 is correct about the idea of people leaving their families for Rosh Hashana, but the ways of Hasidim are strange to me.
