I tried to visit places near UK and Vienna, therefore, I visit France, Netherland, Belgium. And I really want to visit Switzerland. My friend suggested me to visit Italy too. I am ok with cancelling some places, any suggestion?

I travel first to Zurich because Swiss Air offer HK to Milan and can stop at Zurich in between plus $1000.

Thank you very much, Henry! I've seen most of your replies for Europe trip and I gain so much from your experience. I am still thinking about the places of my trip...
