I'm trying to plan a trip from oakland, ca to west palm beach, fl and was looking for some advice on the best route (and approximately how long you think it would take--having never done it before).

One option would be to go I-80 to Salt lake city, down to denver on 1-15, to kansas city, from kansas city to lousiville, lousiville to atlanta, atlanta to west palm.

Having never done this before I'm really wondering if someone can give me an idea of whether this is a do-able route, and if it can be done in 5 nights or if I should allocate more time (I'd like to stop in KC, Louisville, and Atlanta b/c I've got friends in those places--the western part of the trip is more flexible).

Another option is the southern-most route, goign through phoenix and houston--which I've put less thought into, but that could also work.

Thanks for any thoughts.
