A lot of people here and on FB seem to be very worried about reserving a time for dinner on Beyond. I did some research and math to help illustrate the actual situation with the 4 dining rooms:
So the Beyond holds 3,260 passengers at full capacity.
The four MDRs hold a total of 1,378 people (I added these up based on Celebrity's info they provide).
With 2 seatings, that's 2,756 people who could eat dinner in the MDRs in a night.
3260 pax at full capacity - 2,756 max in MDRs = 504 left who would have to be eating in Luminae, Blu, OVC or a specialty restaurant. I think the reality is way more than 504 choose those options in a night. And, on top of that, most ships have not been sailing at max capacity unless it is a holiday or special sailing.
So all that to say, scarcity of seats should NEVER be a problem in the MDRs, unless everyone chooses to eat at 6p, which is just not the case. People's preference for dinner times are staggered enough that this is a non-issue, which is I'm sure what the data has shown for X and why they are making changes - to allow people to have one less thing to worry about (i.e. dinner reservations) - and to just enjoy the beautiful ship 🙂
Its really ok to not have a reservation 🙂
