Sorry, but you are wrong unless when dining you are going to have interviews for those you sit with in advance.
So what are you saying, first night you dont like the table. SO you ask the M'D to move you, and you just moved up the lottery, its his call not yours where you sit next
Are you going to do that every night of the cruise until you find the "perfect table" for you. If you do that, then that says more about you, than those you leave behind!
Take the formal table and talk to people, as you as a passenger cannot pick or choose unless you do buffet everynight and turn up walking round to find a table with your "mates"
