Yeah, assuming cages have locks and what not I think it would be fine. Dogs aren't likely to go and enjoy "quite time alone" as much as say a cat so likely if your home they'll be around you anyways. If they are in the crate their whining won't bother the snakes as they don't have ears.
Laundry room would probably be on an individual basis. Some snakes wouldn't care but some it might stress them out enough to go off feed.
