Ron, I thought that Terraces was two levels (with that great staircase) and that Sun Terraces on Deck 11 was turned into La Trattoria. Back in the "old" days, pax were assigned to a dining room. We chose Terraces on N. Dream/Dreamward, and Sun Terraces on Wind/Windward -- and I agree that the two-level restuarant was nicer. Of course, this doesn't matter today with Freestyle Dining.
Another tip for N. Dream pax -- the obstructed view staterooms on Norway Deck (deck 9) are a great bargain. Roomy, and light still pours in between the lifeboats.
