No, certainly not true. Depending on the parking lot, the average shuttle wait is 10 minutes. Some are a lot less than that. If you would like to monitor the shuttle activity; download the free app Ride Systems to your Android or iPhone. You will be able to track all of the shuttle activity as they service our lots. But there is no sinister plan to squeeze every dime out of you for parking.
It depends on how long you plan on leaving your vehicle parked. Short-term parking has hourly rates that are cheapest at first, but do reach a maximum of $23/day. Meanwhile, long-term A is $18/day, long-term B is $11/day, non-covered express is $9/day, and covered express is $11/day. Every parking lot besides short-term has a shuttle. Short-term is close enough to the airport to walk to the terminal.
Not quite sure whst you are asking, but the fees for parking have steadily increased over the past few years... probably to help pay for the new garage and other new construction
