It isnt about accepting change. It is about the service - all of my cruises on My Time dining feel chaotic and rushed and the waiters are running around trying to keep up. Guests are coming and going. We find traditional dining a bit calmer with everyone in and seated at once, not a group here and a group there.
I havent been able to be accommodated with the same server/same table every night on my past cruises when I asked. I like to get to know my dining staff and them to get to know me (I like lemon with my water, I don't eat fish - and have been saved a few times when ordering). I dont want to have to repeat things every night. And when we book reservations, it only allows us an option for 2, not a shared table (unless we want to eat at 5pm or 830pm)...we enjoy sitting with others.
Celebrity, Holland America, Oceania, Royal Caribbean can do it...Princess can go back to it too.
