We were on the Brilliance...loved it.
The Cafe is open seating. If you get there early, you have your choice of seats. We always grabbed the same table near the window :-). My wife sat and I went to the buffet, and then we switched off.
I didn't get a drink card as I preferred the "free iced tea." We brought along our rather large, insulated coffee mugs, so we were able to fill them with the equivalent of 3 glasses of iced tea,and then take them back to the room.
I love cruising...
