Thanks again, Jim. I typed a response a couple hours ago, but it appears to be lost in cyberspace!
Anyway, when we were on the Navigator in February, they had a service where they took the luggage from your cabin and delivered it to the airport; they printed our online boarding passes also. It was so convenient. If they offer that again, I'm sure that's the route we will take. Otherwise, we will probably try to save time by handling our own luggage on debarkation day.
I just want to get on that ship and sail away for a week! Can't wait!
