I did this cruise in December and will be happy to answer any questions you have: they use the Marriott in Quito for the pre and post stay. A very very nice hotel indeed. If you are arriving on the Friday under your own steam Celebrity will arrange for you to be picked up, providing you let them know what your flight times are. Otherwise a cab costs around $6. It is not far. We arranged our own air with BA/AA via Miami, as Celebrity use Iberia via Madrid.
