Take a day and explore Bay Harbor, it may not even take a day. If you would like to stay here check out http://www.innatbayharbor.com/
It's on the high end, the hotel, shops and spa are expensive. It's beautifully landscaped with million dollar homes everywhere you look. It was actually made out of an old rock quary...amazing what you can do with a bunch of rock and dirt!
The waters are amazing, while your here you must eat at the 'original pancake house', they have Strawberry Crepes to die for!
