Brief thought on the Mumbai attacks

I have no idea who the Deccan Mujahideen are or whether they have ties to 'elements' in Pakistan. One might do well to remember, however, that a luxury hotel in Islamabad (the Marriott) was the target of an attack not all that long ago. Are luxury hotels becoming the, or a, target of choice for terrorist groups in the region? (I'm aware, of course, that other targets besides the hotels were hit in Mumbai, and that the methods differed -- truck bomb in Islamabad, assault with rifles and grenades in Mumbai.)
