I wonder if they've found that offering everyone a variety of set times to reserve just wasn't working out? We had 7:00 reservations on the Enchanted in February, and the first two nights had a LONG line of people with a 7:00 time. After the first night, we were able to book our same table for the rest of the trip, but had to move to a 7:15 time. Hopefully, this will be more efficient.
I also remember that on our last cruise pre-Covid, when it was still Traditional or Anytime, besides the aft DR being Traditional, there was an Early seating in one of the mid-ship DRs, that became Anytime around 7:00 or so.
