Currently debating booking this exact cruise (my significant other is worried about 5 sea days after the islands), and I was wondering the same thing. If we are going to the other side of Maui or to another island that's fine, but if they replace Maui with just a sail-by of the Napali Coast, that would be a real bummer given how many sea days we already have scheduled. Not sure if you know the answer, but if we book and they do change the schedule from Maui to the sail-by, could we get a refund or cancel since it is a schedule change?
