What Sort of Place Would You Want to Visit, If You Had (You need to use the past subjunctive here, thus "had" instead of "have".) the Free Time (or "Spare Time") and the Money for it (or "to Do It") :)?

Have you ever heard about the mount called Kilimanjaro (or "about Munt Kilimanjaro")? :) The mountain is in Tanzania. I really want to go there. About this mountain wrote Ernest Hemingway wrote about this mountain, and it is the most wonderful place in the world, I think. :) (or ", and I think it is the most wonderful place in the world." When you add "I think" to the end as an afterthought, you need a comma before it.)

Also, I want visit the Great Barrier Reef. :) That place (or "location") is the best for diving, I think )!!! What sort of place do you want to visit? :) (or "What/which places around the world do you want to visit?" = more natural sounding)

What sort of place do you want to visit, if you have free time and money for that)?
