A further bit of info. I asked several different people when the other lounges would open. Most just said they didn't know. One person said they didn't know at first. Then, after a nervous moment, blurted out "January or February." Based on what I could see from below of the not yet opened lounges I would say it's going to be at least that long.

One other thing about the AM North lounge. The so-called quiet area, the one with lounge chairs where you can stretch out, isn't so quiet. It's right next to the train tracks. While the train itself doesn't pass there, the cable that moves it runs by there. And it works very noisily. So just a heads up for anyone looking for peace and quiet there.

I didn't try the food options except a bag of chips. The wine was the same stuff they had in the main Al Mourjan and the Platinum South Lounge.
