It depends on the ship, I guess. Some people have managed to cobble together a sort of TD by making plans with folks from the roll call, but it's still iffy getting the same servers in the same location every night. Every report back has been different, and the ship staff is the variable. We are trying the Club Class "fix" this time. We will at least have some control over what wait staff we get, and we plan on making friends with the other couples around us. It's not TD, but this is the option Princess is giving us now (at a not insignificant cost.) Burning through the covid FCC.
