Tip # 3: If you and your family have table mates for dinner, try to arrive for dinner early on the first night so that you can get a good seat at your table, because that is where you will be seating for the rest of the cruise. My family and I love people-watching, and on one cruise, we arrived to dinner late on the first night and ended up seating at a crappy table (because of the location, not the people hehe). It was way in the corner of the restaurant, our tablemates were facing towards the middle of the restaurant, and we ended up staring at the wall for the rest of the cruise! I know it's not really a big deal but we felt so enclosed because of where our table was at.
Or if you want, you can all switch seats each night so that you all can get a different view.
Just a FYI, some cruiselines like Princess and NCL let you choose where you want to sit evey night. There are no assigned tables, and you have your choice of eating dinner in your choice of 3 main dining rooms, or up to 12 different specialty restaraunts.
