How I Wish I Could Visit Hawaii

I have a cousin that lives in Hawaii. She is from my father's side. Both of our fathers are brothers. I see pictures of their place. It is beautiful. I wonder how much is their housing? Is it expensive? I do not know how much is their mortgage. How I wish I could visit them someday. Maybe we could rent a house that is available for sale. Is there, cheap hotels nearby? Have you been to Hawaii? Where is your favorite place to stay?
