If the unscientific data from any of the recent threads on this forum is any indication, it may not be very much.
If Disneyland were a radio or TV station, it would be packed to capacity many hours of its broadcast day with an enormous number of commercials. Extremely cheap commercials. The primary characteristic of its on-air format would be clutter. When that happens to broadcasters, either they thin out the clutter or they risk losing their top-spending accounts -- those who don't want to compete for "ear space" in a shoulder-to-shoulder mosh pit of cheap 10-and 15-second commercials.
