Have never been but I would love to some day. I have a Top 5 wish list...
1. Mount Yoshino in Japan (I've read this is one of the more awesome views for seeing cherry blossoms)
2. Kuang Si Falls in Laos (pretty much Luang Prabang as a whole)
3. Tokyo, Kyoto...I should have just said "Japan"
4. Halong Bay in Vietnam...or pretty much any of the islands in the Gulf of Tonkin
5. Busan, South Korean...such an awesome looking city.
