Having two drivers does not help. It will not reduce the distance, nor the traffic hold ups. Besides you both need to be alert and aware of what is going on around you.

If you leave at 4am, it is likely that you will see the worst possible traffic on the major roads. Even on a Saturday, once you get to the area of Palm Beach, the traffic can be very busy. Remember, it is the weekend, and many people like to go down the Keys for the weekend.

Similarly along the Keys, the bridges can be very very busy. It only takes one accident to hold up the traffic. From friends who live on the Keys I have heard of delays of many hours. This is not to say that it will happen, but you have to be prepared for it, because once you are on the overseas part of the highway, there is no way to turn around and detour or go back. Some of the bridges are very long - one is seven miles long.

Don't get me wrong, it is a lovely area, and I have driven it many times. But you need time; having a strict time limitation will not necessarily work.
