I know how to use google. The response to my search stated International Dining Room. My mistake was to try to find the International Dining Room on the Sapphire Princess (using deck plans). I did not find it (I did not look good enough). Now I see that a large space exits between the Coral Dining Room and the International Dining Room. I saw the Coral Dining Room but did not think to look beyond the space.
Also, I wish I would have looked under the heading "Sapphire Princess Personal Choice Dining". I took that to mean "anytime dining". If I would have looked, I would have seen the name of the traditional dining room. Now I know where to look in the future.
