Ahoy Einstein 
On our last cruise on the Star Princess, we had requested traditional dining at a
table for eight. When we went to the dining room on our first night, we had been assigned a table for four which wasn't the problem -- but it was near the entrance. So we had passengers walking by on both sides of our table which we deemed unacceptable.
The next day we stopped by the dining room and switched to personal choice and
requested a table by a window. When we went to dinner that night, another couple
was seated at the table for six by a window. They were veteran cruisers with 30+
cruises and had many interesting sea tales to tell. A few minutes later, a young couple joined our table and we had the benefit of hearing of their cruising adventures. The older couple had reserved that same table at the same time for the entire cruise and we did the same thing after dinner on our way out of the dining room.
Each night we enjoyed more marine stories from the veteran cruisers and met another
couple to add divirsity to our group/. Our servers were personable and picked up on our preferences and did an outstanding job of serving us during the cruise.
As you know, you may change your dining time to suit your particular situation on any
day of the cruise. We liked our experience with personal choice that it will be our only
choice on future cruises.
