We were there last week, and will return in a week. Notably, Diamonds get full breakfast in Glass (a welcome reversion of the obnoxious surcharge for hot items). Moving the omelette station to where the bread used to be is a good thing, as the former location in the buffet line didn't work. The old location caused huge backups and it was quite difficult for people trying to access buffet items nearby, and difficult to tell where to join the queue. The downside is that there are far fewer bread items (no gluten-free area, for example).

Worth noting is that the filtered water dispensers in the rooms don't seem to ever have their filters changed. We marked the filter in our room right after it was installed, and the mark was still there.

I think the new lounge should have giant flat screens placed on the walls, displaying live feeds from rooftop cameras. That would at least recreate to some extent the experience of the windows in the old lounge.
