Well care to offer a rebuttal? STL v ORD which one is better/worse?

Speaking of hotels from an efficiency standpoint why don't they book the in terminal hotels where available? Such as the ORD airport hilton or say the MCO in terminal hotel or the DTW in terminal hotel? No van needed. Just get up, clear TSA and off to the gate you go. Sure its expensive but it gives the highest chance of the morning flight going out on time.
