This thread is so depressing.
I understand everyone has different preferences about how to spend their hard-earned holiday money. But to rule out places even if someone paid for your holiday?
I had NO idea so many people would not consider Australia because of ...spiders. Or put a blanket 'no' on Africa, Asia - or Japan for example. I mean Tokyo is crowded yes but Japan has so many other exceptionally peaceful and beautiful places to offer. How do you know if you never went there and saw for yourself?
I'm sorry to say this but it all sounds so small-minded, to never consider going out of your comfort zone. I went to Marrakesh and did not enjoy the harassment or the chaotic markets, but what it did was open my eyes to a part of the world I had never visited. The architecture was amazing and left a deep impression. I can't say I'd go back again but I'm happy to have been.
Similarly, I don't like the idea of Dubai but I won't say I'd never go there, I'm curious if a visit there would confirm my beliefs about it.
Horses for courses, I guess.
