Been a WW member for a while, through their recent growth period. From what I can tell this is part of 'the strategy'. Start a new office, make it incredibly shiny/nice/very fully staffed, fill it up, then start cutting back to something more sustainable.

Note that this isn't necessarily a bad thing (unless you work for WW). Starting by crazy delighting your customers to get an initial bump, then cutting back to something more sustainable isn't exactly a groundbreaking strategy. It's a bit reminiscent of what Uber does in new cities.
