I've read two articles in the last two days that appear to be written by or about "experts". It makes me laugh at what some people will throw out there.
Rule of thumb in the Windjammer: make sure there is a sole of some footwear between your foot and the floor.
The one that got me this morning was a couple that found it cheaper to retire on a cruise ship. OK, sounds good. The wife is a retired accountant and crunched the numbers. She found out what most of us know. That's good. What she missed is how much more she would get for free IF THEY STAYED WITH ONE CRUISE LINE. They are bouncing all over, which would drive me nutz.
Unpack, stay for a loooooong time: I'm good.
