Which is fine, but doesn't explain why each gate is openable from "inside" the balcony walkway area (making it possible to get from the balcony into the CCR, GF).

They're definitely not alarmed (I walked between the lounges myself), and there are no signs on either the CCR or the GF balcony saying "no entry" - just a sticker (rather invitingly) saying "turn to open". As it stands, I don't see the deterrent and had I not checked, might have been tempted to use the route as other passengers seem to be doing.

(This is separate from the stairs that lead directly from the gates to the CCR, which is more forcefully marked and doesn't have a handle on the outside - although I suspect the statement that that gate is alarmed is an empty threat!)
