I'm assuming that stvr is talking about Hilton's ability to pick your room off a floor map - this is unique compared to either Hyatt or Marriott (which all have mobile check-in abilities). Still though, I wouldn't want room selection to be like airplane seat selection, and I hope that Hyatt doesn't try to emulate Hilton on their "guest-friendly" and "flexible" policies (which are really just thinly-veiled attempts at reducing employee headcount).
