I love vacationing at the beach. Hawaii is the only US state composed of islands
I love Hawaii, is is my favorite state in the USA.
I have never been, but want to go. It is the only state located outside of North America.
I did not know that. How many islands are there?
There are eight main islands that make up Hawaii. 
What is the biggest island?
It is usually called the Big Island or Hawaii Island to avoid getting mixed up with the state.
