Panel labeling conventions
Rooms without a clear, unlikely to change, definable purpose (i.e kitchen, bathrooms, etc) are better referred to by compass direction than current function (2nd Fl NW rather than christy's bedroom or guest room or office...) and likewise if there are multiple bathrooms per floor, say.
Or, go commercial, print out a floorplan, assign numbers to rooms, and use that. If doing that, convention is 3 digits and the first is the floor, even if there are not more than 9 rooms per floor.
(not that it helps with inspection, but it can help YOU or future owner if you also label each outlet/switch with a breaker number - under the faceplate if you don't want to see it normally.)
