Best place to park at Bush?

I’m flying out of town for three days and would like to know the best place to park at Bush. To me, best means easiest to get to the terminals from, but great deals are welcome too. Last time I flew I parked at eco park, but had to wait for a shuttle to fill in order to leave, then it had to drive to the actual airport and went to three other terminals before mine and it was 30 minutes from the time I parked until I got off the bus.
