Decreasing the lines at theme parks

  Even though the Express tickets have somewhat decreased the endless waits at the Disney Worlds and alike, I still think it can be done in a better way: When you enter the park, you should be able to proceed to a computer screen, on which you can enter your itinerary for the day. The computer then calculates and reserves the time slots when the specific rides are available. This way you can get the most out of your day. Granted, it does make it seem like work, having to follow a possibly tight schedule but anything beats standing in line for an hour for some silly ride.
