Odd choice of target if they were after Iraqi western contractors - I usually stay in the Grand Hyatt because the clients are mostly Arab businessmen, whilst the high-visibility contractors are usually lined up at the bar at the xx and yy hotels elsewhere.
bit of an own goal methinks. a shame as having worked and visited Jordan it is a lovely country and the people very friendly towards westerners. i stayed in the Le Meridien when there last. i knew of a hotel 10 mins walk away that was full of ex pats and US embassy staff. maybe the one your talking about 4(T)?
God alone knows what was going on - Jordanians have denied any warning was received, someone or other claims an Israeli official delegation staying in one of them got a headsup from the Jordanians, the Palestinian DMI was killed in one of them...all very spooky. I'm going with the simple option - it's the Iraqi insurgents' deep operations cell.
