​A hotel with two-way mirrors only. The people on the mirror side pay 0.1x the normal rate, the people on the see-through side pay 100x the normal rate. The mirror side gets a cut of the see-through side’s rate.

If you stay in the mirrored side and no one wants to watch you, well at least you get a cheap room wherever you’re staying. If someone is willing to pay to watch you, you make good money and some voyeur gets their rocks off. Room allocation is random to avoid stalkers, except for maybe some general description like “Superior Queen with Exhausted Toddler Parent View” or “Executive Suite with Aspiring Influencer View”
