If
DVC says
“commercial renting is prohibited” but never defines what “commercial” means, that creates contractual ambiguity. Contractual ambiguity itself is not illegal however legal problems exists when:
Enforces it selectively or inconsistently
Uses it to justify punitive penalties or forfeiture
Refuses to define the term while still punishing conduct
If contract law rules don’t apply, contracts are still protected by the FTC and state attorneys general. What is the basis for why companies get their hands slapped the most by either of those entities?
Vague terms causing consumer harm
They didn’t update their policy because, at this point, it’s just a scare tactic and it doesn't matter. Disney’s not stupid—they know they can say whatever they want, but actually enforcing it is another story. I’m no contract expert, but most contract disputes are forced through arbitration, so you’d never hear about it unless it turned into a class action lawsuit.
With that being said, if you’re renting thousands of points or renting as an LLC, it would be hard to argue that you’re not renting commercially. IMO these are the things that Disney is looking for.
My curiosity leans more toward places like David’s or the
DVC rental store. They’re clearly commercial companies, but they act as rental agents and don’t own any points, so when, if ever, are they held accountable? My guess is that since they’re all still playing the game, they don’t believe they’re accountable.
