That should be a great cruise.
Ten days is my favorite length on a cruise , although I have been doing 7 day cruises the last five years in October, with no flying, or hotel stays, because of my wife's dementia.(Alzheimer's)
As a bonus you won't have to put up with our CDC. -Tom
Sounds like that format serves your current needs well. We are late 60s and have not cruised before, except some Navy service and a warship. Looking forward.
