...means that they can get you an early check-in as soon as you walk up the street from your old, cheap crappy hotel.  Of course, the downside is that, unlike your crappy $90 Econolodge hotel which at least has free in-room wireless, even if you have to fight to get it working, your $200/night downtown ritzy business hotel charges you $10/day for in-room wired Internet access.  What a rip-off!
