Many properties have games rooms with pool tables and air hockey, but ours also has the full size 75 game stand-up arcade along with tons of stuff for the little kids. These include a doll house, princess dresses and superhero costumes and tons of fun toys for infants on up. We haven't seen many other houses that really have fun stuff to keep the little ones busy while the adults recover from a day at the parks.
We also wanted a place that was much nicer then ours at home, so we went all out with a professional decorator who insisted on very high end furnishings and Disney themed rooms and a fully equipped games room. She even insisted that we re-engineer the Air Conditioning and provide additional insulation so that the game room would be nice and cool.
