funny you asked that question. I have not "cruised" alone yet.
But I have one booked on August 23rd alone. My DH just passed and I want to just go on a cruise, so I booked one. I'll have the room to myself so that will be great.
I'll be cruising more alone in the future also - or I want to - we'll see what happens.
I know a lot of the CM's so that part will be the same - in a nutshell, I guess I won't be alone in that sense.
