Deck 14 Suite Hallway - door to Sky Lounge?

It looks like there's a door connecting the suite hallway to the Sky Lounge.

Is this accessible for guests in those suites, or is it strictly for crew? We'll be in that hallway in a few weeks and it looks like an easy way to get out to the Sky Bar to grab an afternoon drink for our balcony.

I have seen it used as an emergency exit when the door to the Sky Lounge jammed once, but otherwise I have never seen anyone go in or out that door.

Since access to the hall to the Suites on 14 is restricted to those in the Suites, it doesn't seem logical that a door from a public space would be open thus allowing access to the hallway from the lounge.
