I posted many more details (and a few videos) on the "Just back on Flora" thread in the Flora roll calls but will try and summarize here. It seems like many of the other reviewers' comments may have been heard and addressed as we didn't experience those problems.
From pickup at the airport to dropoff at the airport, Celebrity handled the logistical details seamlessly. We did the 10 night package and enjoyed the precruise experience at JW Marriott, the Quito city tour and lunch, and to a lesser extent the dinner (there were not many choices off what is an extensive menu). The charter flight was fine, the food served on it was very good. Yes there is a line when you arrive at Baltra to go through immigration but you do have access to restrooms and since you can travel with liquids, you can certainly bring a filled water bottle. The VIP lounge is not all that exciting but it was fine for the short wait while they sorted out the logistics and was a good time to chat with your fellow cruisers.
The ship was beautiful - we were in 503 which was a regular verandah cabin and we thought it was spacious for a cruise ship cabin, especially the bathroom. We did not experience any issues with the sinks or the toilets and once I learned to put the bathmat down just as I opened the shower door, no problems there either. We found the mini nightlight under the sink in the bathroom was adequate for our needs, so never needed to turn on the main light- if you did I can see where that could definitely wake the other person given the glass wall. The sliding door to the balcony was very hard to open or close but without me saying anything to anyone, someone came one day and fixed it!
