If it were me, I would at least want someone to be able to check on them daily that could get ahold of me if there was an issue. Some people do maternal incubation the entire period successfully, so I would be less worried about that and more worried about the actual laying so that the mother could be taken to the vet if she gets egg bound. I haven't had a BP get egg bound on me yet *knock on wood* but I have in other species. Not being around for over a week, who is going to be giving them water both to drink and keep the humidity stable? If the husbandry isn't on point, that increases the chances that both mother will egg bind and the eggs will go bad. If you have somebody that is caring for them but just doesn't have the knowledge or confidence to pull and setup eggs, I'd say things will probably be fine.
