Aren't hotel room locks already easily cracked? IIRC the post you're probably thinking about was the fact the reprogramming port for hotel use allowed an attacker to do gain control. This is an implementation problem with the hardware attached to the door, regardless of key technology. Even with poorly-protected service access interfaces and magstripe keys the incidence of malicious attack doesn't provide economic incentive for hotels to do better. Bluetooth based locks may provide incentive to swap out all the existing poor security locks in a building, but there isn't anything preventing the computer security of the new locks from being even worse.
