Not just any cruise, but one with all of my siblings + spouses & my parents.
Anyhow, the destination & time has changed a couple of times (coordinating so many schedules and such), but the essential fact of taking a cruise together is still intact.
And really, who could turn down a week with these people?!
(My brother & his wife took this picture when they found out about the cruise. It brings to mind a certain saying about picking your friend's nose, but of course that saying doesn't really apply--you can pick your friends, and you can pick your nose, but you can't pick your family.)
