Dare I say, one of the nice things about beekeeping is that most of the time you can manage without needing a "fill-in" to cover for you when you go away on vacation or can't get to the hives for one reason or another. Of course, when raising queens your're on a tight schedule, but generally speaking, it won't damage your yield or your hives seriously if you remove and extract your honey a day earlier or later. So too with treating for varroa or some of the other maladies bees can come down with, a day or two sooner or later usually doesn't make too much difference.
