We sailed the Glory in Feb. of 07. If I recall correctly formal nights were on your sea days. Our cruise fell on Valentines day so I booked the Emerald roon for that evening. It was excellent, and by far the best meal I have had to date. We dessed as you would for formal night in the dinning roon. Plan on at least 2 hours for dinner. There are many courses, and you really want take your time and enjoy being spoiled. You will enjoy it. I made our reservations in the Atrium lobby as soon as we got on the ship. They set up a table and allow you make the reservations right there.
Hope this helps.
Enjoy your cruise
