Let me expand on the other review already posted here [on Cruise Critic].
Let me state right up front that this is a "NOT TO BE MISSED" cruise.
Celebrity really has their act together on this offering. Don't even try to book the cruise yourself and try to do the land portion on your own. This isn't one of those "start to board at noon, sail at 5pm" cruises. If you don't arrive on the correct TAME flight, you are not going to get on the cruise....and you can't just buy a TAME ticket from the US..they don't take credit cards...it's very tricky. Just pay Celebrity to handle things (the 10 or 11 day options). They meet you at the airport, transfer you to the hotel, give you a full day tour of Quito and pick up the baggage outside your hotel room on Sunday morning at 5 AM (not a typo)...which is Ok because you have to leave at 6am. The next time you see your luggage is in your cabin aboard the xPedition, unless you happen to spot it on the zodiac on it's way to the ship. Everything comes to and leaves the ship on one of the four zodiacs..you, your food, your luggage, and all ship supplies. The xPedition never docks at a real terminal.
