In one of The Kane Chronicles books (I can't remember which), it is mentioned that a guy who had a strong connection with Egypt went to the Land of the Dead when he passed. In other words, personal beliefs do factor in one's destination in the afterlife.

Similarly, in The Throne of Fire, Sadie and Walt come across ghosts unable to move on to any afterlife because their bodies were not given proper funerary rites. So, my guess is personal beliefs determine your afterlife but the funeral rites have more precedence over them.
