I told my wife years ago that if she wanted to go on a cruise I would fly to wherever it was going and meet here there. I get claustrophobia around crowds of people.
I now feel flying is not a desirable experience. Remember the days when you had plenty of room. Drinks were free and stewardesses were friendly and cute.
Other than disembarking, there really aren’t big crowds on the ships......I’ve been on over 80 and I do have a little claustrophobia.
