Place to Go!

I am looking for a place where I wanted to visit someday. It may part in Europe or in States. I wanted some suggestion which is place the best to go for a visit. It would be my appreciation of any suggestion. I know everybody would love to see the beauty of the world and wish that someday we could go visit once in a lifetime. I am searching the same time but any suggestion would be a help too. I will wait for any response of my post. God Bless Us All.
