the GC is really neat to see. ive been there a number of times, north and south rim and enjoyed it. i did the helicopter tour to see more faster and that was worth the money to me. if youre heading from florida, you might want to hit I-40 and check out Santa Fe then shoot west on 40 and see the Petrified Forest then go up from Flagstaff to the south rim then you can work your way west and see Bryce and Zion Natl Park and then go up thru Utah northeast and see the Arches Natl Park then go west into Colorado and drop down Hwy 550 which is AMAZING and go thru Silverton and Durango. I've done that route a few times and really got to see some stuff. Then you can work your way southeast and check out Carlsbad Caverns and then drop down to I-10 and shoot east back home. That also put you thru San Antonio if you have the energy left to see the Alamo and Riverwalk. You'll be going thru New Orleans so you can hit Bourbon Street, drink a Hurricane at Pat O'Briens and catch some Mardi Gras beads and then go home and sleep for a week....
