The users creating these itineraries, who are essential the content creators, receive star ratings and comments based on how well that particular itinerary was for a user who decided to try the itinerary. (I.e John creates a 1st date itinerary. Mike, who is looking to plan a 1st date selects John's 1st itinerary. After going on that date, Mike really enjoyed it and then goes back to give John a 4 star rating and comment on how great his itinerary was). For future iterations badges an points may be an option.
