Great! There’s no reason not to clearly disclose those fees up-front other than deception.
AirBnB is the worst at this. A vacation rental is $200 a night, so you’d assume five nights would be $1000 plus tax. But then add the cleaning fee, the service fee, the booking fee, the hosting surcharge, the surcharge fee, and a half dozen other junk fees, and suddenly it’s $375 a night. Plus tax.
