I can see what you mean about the places you've *almost* bean to. The closest for me would have to be The Loevre. I had one day to visit it, and I only found out what I got there that it's closed on Tuesdays! (If I remember correctly)
I've seen eleven on the list:
Hong Kong harbour
Leaning Tower of Pisa
Yangtze River cruise
In the end, the question you have to ask yourself is: are you talking to me, or are you chewing a brick?
