Someone probably has a more accurate number on this, but I suspect the average total cost of cleaning a room is about $20 - people for the room as well as laundry, supplies, electricity etc. The $5 value given per voucher is mediocre. I rarely see these tags hung on doors.

If they actually do want to create change they should make a splash on the top end. All $15-20 (or equiv points), and increase property participation (for brand image), and then slowly ratchet down over time. Likely back to $5 in like 5-10 years, but now with considerable more buy-in, and actual net effect.

If they actually give a rip, that is.
