Our first 7 day cruise (we've been on 4 and 3 day cruises) is coming up in November. I think I've got a handle on when to book Palos for the brunch and tea. However I'm not sure about the evening meal. On the four day we always did the last night. On the seven day I'm not sure what all to consider. I've heard there are formal/semi-formal nights that may or may not have special menus only available that night. Can someone give me some tips on booking Palo dinner?
