Ship: Amazing! It's best described as Feng Shui at sea. There are strong elements of earth, water, metal, wood & even fire (with the hot glass show) throughout. Modern, edgy art work, contemporary bars, retro lounges and lots of windows and light throughout. This is definitely a "WOW" ship. There's a full size tree suspended in the center atrium, a section dedicated to improving Planet Earth, lots of alternative restaurants, and plenty of shops on two decks.
Aqua Spa Class: Worth the cost. Cabins come equipped with a hansgro multiple head shower panel, fresh flowers & champagne, robes, slippers, fresh fruit & free bottled water daily, 32" flat screen TV with yoga programs & new age music selections, balcony, a menu of pillows, all on the deck below the Spa. You also have an Aqua Spa concierge and unlimited use of the relaxation room & persian gardens.
That said.... There are a few kinks Celebrity needs to work out... Persian gardens is boring. It's basically a steam room, relaxation room & sauna (which didn't work 1/2 the time.) We used the free sauna in then changing rooms more often because it worked. Paying $22/day or $99/cruise is a joke. This should either be improved or free to everyone. We pre-booked a spa package in advance, but needed to set up times once we got on board. At 11:30 we boarded and went straight to the spa concierge. After waiting in line 45 minutes, it took her another 30 minutes to book our combined 10 massages. And we made it easy - we said book us everyday for 3:00. 30 minutes later....it was done but there was a LONG line behind us. (One person making appointments.)
