I have been there twice. The first time, we disembarked between 9:00 - 10:00 AM and were brought to the airport and waited for the charter plane to arrive with guests leaving on the ship that afternoon. We departed Baltra early afternoon and arrived back into Quito around 2:30 PM. The second time, there was a mechanical issue with the charter plane before it left Quito, so we did not disembark the ship until around 10:00 AM. Celebrity bussed us to a beautiful resort where we were served a wonderful lunch and had the opportunity to go on another "excursion" with the naturalists as well as time to use the pool. We did not arrive back into Quito until about 9:00 PM that evening. It sounded like delays with the charter flight are not unheard of, so I would not book a flight until very late evening out of Quito.
