Solo discrimination by the cruise lines

I'm actually a little surprised that it's taken me this long to write about how badly single cruisers are dealt with by the various cruise lines. I guess as I've never tried cruising solo it's sort of flew under my radar a little. So for all the cruisers out there that cruise on their own I apologise it's taken me this long to comment on it. As you've guessed by now from the title of this post I definitely believe anyone trying to do a solo cruise gets the short end of the stick. But how bad is it really?
