No, ban it unless the owner is onsite. Simple. It still allows people to make some money and there's some accountability for who you're bringing into the place.
If someone wants to run a hotel/motel, they buy or build one.
I know renting shacks and beach houses has always been a thing in some areas, but not on a grand scale. The people who did that before will still do it via personal terms on a local basis where the risk falls upon them, but a ban without the owner onsite immediately cleans out the speculating scum who've broadened it into full time residential areas and buildings that were never set up to be hotels.
