I don't think the real problem is being addressed. The real problem is forcing someone trying to do some work into the same space as a family off to MCO - they have different needs and wants.

My fix would start with the physical space. First, the Concorde Room stays exactly as it is, exclusive for F pax and GGLs

Then, you sort out T5A by vibe. You create 'The Library', a proper quiet zone for working. Another of the spaces becomes the main adult 'Social Hub' for food, a G&T and a chat and you'd wall off a decent-sized area of it to make a properly sound-proofed 'Family lounge' to contain the chaos. Everyone gets the atmosphere they actually want without getting in each other's way.

The clever bit would be to add a simple tech layer to make status feel worthwhile, where a decent BA app becomes key.

A GCH in the Social Hub could use the app to unlock a menu from which they can order a proper main or a glass of high-end champagne from an exclusive menu, brought to their seat, while a Silver next to them still gets the decent buffet or alas pay for the stuff that GCHs get for free. GCHs could use the app to book or access a private work pod in The Library or get priority for a shower.

The idea would be to use tech as the status differentiator within a shared space, where the space is focussed on the environment that suits you best.
