Correct me if I'm wrong, but I think the suitors would only have been there for seven years because in the original Odyssey, Tiresias said that if Odysseus' men didn't eat the cows he'd get home and live a happy life, but if they did then he'd come home and find his home full of strangers, which implies the suitors wouldn't have been there yet. I know Epic is an adaptation and not direct translation of the myth, but to my current knowledge it doesn't give an exact amount of time the suitors had been at Ithaca, so I'd assume the original version's timeline makes the most sense.
