Ouaha, Hawaii or similar?

My fiancé and I are having the big day in September, but delaying the honeymoon till October 28- November 3rd. She has her sights dead on Hawaii, but as I keep looking up flights I keep thinking we need a back up option to that might not be so expensive. What would be similar in the USA? (We’re on ohio) I have no clue where to look for alternatives and at least want them to be somewhere she would consider as a back up.

Thanks!
