At large resorts, like SSR or OKW, where there could easily be 100 units turnover a day (substantially more on Fridays and Sundays) and each unit takes even only 5 minutes to inspect, that is 500 minutes, or 8 1/3 hours of nothing but inspecting. And probably longer for larger units. That would be a minimum of 2 full time supervisory positions, probably 3 to 4, to be added to payroll and dues.
Just do it and keep the rooms "well" maintained. That is simply the way it should be. No ifs, ands, or buts. Based on the total number of points at OKW, the cost would be totally insignificant.
