Florida to Yellowstone, Grand Teton, Grand Canyon and back

The thing is, one does not see Yellowstone in a day. You'll miss 90% of the highlights, not to mention the hidden gems, etc., that way. Unless you are into marathon driving and have 3 or 4 drivers who can rotate so you can stay on the road nonstop until you get there, I don't advise this time frame. We used to spend 3 weeks roundtrip to get just to Yellowstone & the Tetons from the Chicago area! And that of course did not include the Grand Canyon, or much in the way of sightseeing on the way there & back.
