As you probably know this ship will be refurbished and re done and a new one is taking its place, I believe, in 2020. The ship, thus, looks a little tired, but it is very clean. The state rooms are among the smallest I've seen, even the suites, but you won't spend a long time in the room. My only criticism would be the snorkeling equipment, the fins in particular are lacking, they don't have inventory in the most common sizes and the same with the wet suits most of which show a great deal of wear and are broken in places. Fins and a wet suit are essential in this cruise and at this price the equipment should be in top shape.
The bar is another thing that needs minding. There is only one bar and it's the hang out place when you are cruising or after excursions. The bar has very limited selections and the bartenders are hit and miss with the drinks.
Other than that Celebrity provides a great experience from the moment you touch down in Quito. The places they take you, the food, the hotel, it's all done very organized. Staff is all terrific. The ship's food is very good, not fancy, but fresh and delicious. The meat is pre cooked before it reaches the ship so you may want to opt for the sea food items which are local and fresh, specially the langoustines which are a delicacy State side and quite expensive.
