We too sailed Galaxy in November and the first night is open seating. They try to guide you to early 6:30 seating, but you don't have to do that especially if you have late seating anyway. The second formal night was changed too the evening when you depart Margarita Island from the Aruba night. Celebrity finally has open seating in the Main dining room or breakfast and lunch when you are at port.
The first evening is so exciting and I wish all evenings were opening seating like this. A real important suggestion is that you check where you will be sitting all the other evenings. We did not and had to sit next to the kitchen door and entrance. We missed all the see and be seen stuff in the main dining room. It was a real mistake. We understand you can change your seat if you check it out right away if you board in the afternoon. Soon to do that on the Summit Jan. 14th 2002!!! Kassie
