What if it isn't an obvious problem but just not as good as pictured online or varies from what is pictured online (i.e. has comparably both positive and negative features) and the hotel refuses to or is unable to move one to a different room either in the same category or a better category? Would one be within one's rights to just leave the hotel for another one? For luxury hotels, objective problems should naturally be rare so I should probably rephrase my question to address quality and suitability to one's subjective needs.
