I'd caution that the app has been a little inconsistent with how private dining shows up among the resorts. While it doesn't say "closed" like some of the resorts, the actual notes still say it's unavailable. BW has displayed the same for awhile now, just as another example - but private dining there remains closed.
I'd really like to see the private dining hours show up in the app like they do for YC/BC and GF (the resorts that are currently offering in-room dining) to support it's actually happening.
That being said, offering in-room dining at CSR (like they did at the two other NBA resorts) upon reopening would fit the pattern. Guess we'll find out soon enough!
fingers crossed.
