It's worth noting that this wasn't some crummy flea-bag hotel - it was a nice western hotel. Which is probably why it was targeted as it caters primarily to westerners.
I've stayed at some hotels in Indonesia that had pretty impressive security (including the Marriott in Jakarta that was bombed several years ago) and it did make me feel 'safer'. But that security was aimed at stopping a car-bomb or lone gunman.
I've yet to see hotel security - anywhere - that would reliably stop a gang of eight or ten heavily armed suicidal radicals that stormed the entrance.
