I think the best protection as a consumer is to simply not give business to an organization that doesn't operate how you like. Look at all MyVegas at the App store and see how they advertise. They emphasize on the opportunity to get "Real Rewards". They don't advertise buy chips for rewards this is because it is implied as a consumer and not their guarantee. Wynn is no different and when they have to make a business decision that will upset their clients but keep them from bleeding more money then I would bet on them not bleeding money. Plus because how careful they were with their legal talk are protected.
