Your best bet is on the first night, IF you like your table and waiters, then ask the Maitre’d/DR Mgr if you could have that table every night. If your a private table, it’s easier than a shared table, unless all parties agree to share that table too every night and speak to the DR Mgr/Maitre’d also.
Seems each ship the MDR is run a little differently, but the first couple of nights getting people settled in tables seems to be the most difficult for them. TD was a lot easier on the staff, I think.
Anyway, we were able to do that on all of our cruises so far, since the restart.
Make a reservation for same time, same MDR every night and check on the 1st night.
