We're booked in the new Aqua Class cabins being installed on deck 11 of the Summit this upcoming Februrary. We've only sailed on the Millenium class ships always in Concierge class. The main reason for going to Aqua Class this time is the location of the cabins and dining in the Blu Restaurant. For those of you who dined in Blu on the Solstace class ships can you share your experience? Is Blu open or assigned seating? Does Blu have the formal nights like the main dining room or is it "business casual" for the whole cruise? I'm assuming the food is excellent.
