I live abroad and travel a lot and researching for my holidays is one of my hobbies.
And I'm allowed to say that I won't go back to Venice for various reasons.
What I find odd on these threads is when people who are giving their opinions, because they've been somewhere and didn't like it, are shouted down by others saying they're wrong. Clue is in the word "opinion".
I didn't like Venice. I loved Rome. Not keen on going back to Barcelona, loved Madrid. Went to Majorca when I was 19, won't go back. Didn't like Seattle, loved Vancouver. Etc.
The difference is, I haven't belittled anyone's opinions which aren't the same as mine. I've just thought "oh, there you go, I loved it".
