I think a lot of guests don't bother to read the online reviews -- they're booking on the strength of recommendations from their travel agent or from friends and family, all of whom last visited 'Ohana during its glory days, and don't realize how much it's gone downhill.
In fact, we were looking to book a couple of our perennial favorite TS meals on our upcoming trip, and almost made the mistake of not checking reviews ourselves, since we thought we knew what we were in for. It's a good thing we did check them, as recent reviews and sweeping cuts to some of the menus resulted in us dropping some of those plans in favor of CS meals. We'd already cut 'Ohana from our must-dos after diminishing experiences over the years culminated in a downright terrible one in 2018, but now that we've seen the latest downgrade, I think we can banish it forever, thus saving ourselves hundreds of dollars worth of "unmagical" dining experiences. Thanks, internet!
