There have been many very good detailed reviews of all the excursions and about the ship, I will just add a few things.
We flew from Portland, Oregon via LA and Miami. One ticket was free with flyer miles, we kept telling ourselves that during the 10 hr layover in Miami. We had the same attentive courteous service from all the Celebrity reps as others have said.
We chose the 10 day with the pre and post cruise nights in Quito.
We did the cruise with only carryon luggage. We each had a duffel bag that was within the size limits of carryon, plus a backpack. We took 3 oz or less bottles of bug spray, sunscreen, etc. What we packed: one pair docker pants, 3 polo shirts, 1 long sleeved lightweight white shirt (ours were sunscreen 30SPF), 1 jacket, 3 pair shorts, t-shirts/tank tops, 2 swimsuits and 5 pair underwear. For shoes we took Keen/Teva sandals, tennis shoes and a pair of slip on canvas shoes for wearing indoors. We purchased hats at the first town, there may be some available on the ship but they were out when we went. We wore the dockers and a polo shirt on the plane and in Quito. We had laundry done once on the ship, mid-way in the week. It was about $25 for quite a few items and we got them back the same day.
On the morning we flew to Baltra, check in was in the library.While we were there we located our bags (we checked the duffels for that flight) just to be sure they were there. One group of three got to Baltra without their bags not sure what happened but it took a couple days for them to get there.
It was nice to have drinks included in the price, as well as tips. We had good service and enjoyed all the food, it was fun to try new items.
I had a dental situation come up the last full day of the cruise, I broke a front tooth crown. It didn't just come off, the tooth post underneath broke. I talked to the ship's doctor, she said they would make an appt with a local dentist (Santa Cruz). After the morning's excursion, a naturalist (Sofia) went with us to the dentist and translated. The dentist was able to drill another post and reattach the crown. One hour's work, $60. Sofia really went above and beyond customer service to help us, as did the other Celebrity staff in setting up the appt and so forth.
This is not a cruise to relax, it is to see as much of this unique place as possible, while preserving it's beauty and character. We are so fortunate to have had the opportunity to do this.
