Contact your congressman, perhaps they will set the definitive rules for when a park can call themselves a resort, when it is acceptable say you are pet friendly. Maybe they could set the standards by which wifi is to be judged and perhaps the courts could review each photo and decide whether or not it represents the park.
Or, maybe they should just outlaw advertising altogether. Today I had a bowl of Cambell's Chunky soup, and I didn't think it was that chunky. Tonight, I might watch a TV Drama, and sometimes I figure them out in advance, so where exactly is the Drama?
Advertising is not a substitute for research.
