What time do dining reservations open at 45 days out?

[KKB]

Midnight EST?

Thanks!

Midnight EST supposedly but sometimes anywhere from 5 to 30 minutes earlier than that.  When the app crashes, your TA can make your reservations for you or you can call VV the next morning and they can do it.  Note that I said "when" and not "if."  4 VV cruises, and the app has crashed every time while booking dining.  I usually get 2 or 3 nights booked, then it dies.

Midnight EST, though you may get them around 11:45p ET.  Use a TA because they can get into the booking engine to book your dinners much faster than you will with the app.
