Do they just have one early seating and one late seating?
SS Norway (12 times) '85 - '97; Radiance OS 06/01; Island Princess 11/04, Grand Princess 11/04/05, Golden Princess 7/21/06, Golden Princess 2/24/07, Explorer of the Seas 12/23/07, Island Princess 11/15/08
Plus they have altermative dining rooms as well as the Windjammer, which is a buffet for dinner. For the alternative dining, you'd need to make reservations. If you go to the buffet, no reservations needed, just go when you wish.
