We are in a DV cabin on the Venus in September. I was eligible for excursion booking on July 25th at 12 pm Pacific time. I started looking at 10 am, but it was not until 3:01 pm eastern when it opened. I was able to get what we wanted though. I called Viking to see about dining reservations....but I can't do that until Aug 1. Last time on board we never were able to get reservations at Manfredis. Did not even know they "guananteed" DVs "priority" reservations. Maybe this time we will get lucky?
