I ... was just concerned about this boat
Everything that someone loves to little tiny pieces somebody else detests. The restaurant you love? Many people hate it for a wide variety of reasons. The movie that you watch over and over again because it speaks to you ...? millions loathe it. Your "go-to" book for long, cold, boring winter nights? Hundreds of thousands have thrown it away. Your own "must-see TV"? millions cannot watch without cringing.
Does any of this make you rethink?
Then why would you suddenly worry about what people think of a boat?
How dare u assume that i want a bad vacation
I'm sure you don't ... consciously.
But the interesting thing about human psychology is that we tend to color out own experience based on the subconscious remnants of others'. What other people say can - and often does - affect how we perceive something. You may be one of those who [like me] deliberately discounts other peoples' opinions as subjective fart gas, whether those opinions are glowing or actually incendiary. But chances are good that you aren't.
Chances are especially good that you'll take others' negative opinions into consideration because you have already declared a "worry" about the validity of those opinions.
Bottom line, as Ed said: you'll have the cruise you expect to have. Expect a marvelous time - by YOUR standard of marvelous - and forget what everyone else thinks is bad. Forget what everyone else thinks is good, while you're at it. They already had their cruise, so you don't need to have theirs again. Have your own.
SIG: If you're going to create the drama, at least supply the popcorn.
