JOC we are a family of 3, never have we been seated alone. Believe me we don't change any of our family habit. DH still sits at the table yelling at my DD to eat her food and I give him the same knock it off look. I carry in my own glass of wine or drink, order way to much food cuz I like to taste everything. DH lets out a burp every now and again, saying excuse me of course.
If you do have to share a table just explain to your dinner mates that you all like to eat fast and go, I am sure they will not mind. We do like to have dinner at Palo and Topsiders and few times a week. So on the first night we explain to our tablemates not to take it personal but we like to eat all around on the ship.
If you are going on the Magic they do serve dinner at Topsiders and you can have a table to yourselves. Just remember before you leave the ship to take care of your your regular rotation servers. They have been there waiting for you every night.
Sending Pixie Dust your way in hopes that you get the table assignment you want.
