Oops I should have seen this thread a bit early.. We also first planned for Florida, thinking about the crowd we postponed it
Broward county vote counting machines and butterfly ballots are also a great sight-seeing place to learn how the world's most advanced nation could use substandard 20th century system.
Hawaii got really good climate in December. But it will be more like relaxed vacation. Kids may play in beach, I don't know how old is your kids. There are colorful fishes in knee length water. You can try snorkeling. So many good trails to walk and natural beauty to explore!!
I will go to Hawaii for sure.. It's in my list..I am just yet to decide between Florida or Hawaii for this December..
