that is a HUGE trip!! how much fun!! is this a college tour?
new orleans, my favorite city (transplanted alabamian living in the midwest here). so many things to do, so many great restaurants! definately see the quarter if you have not been. but plan a trip outside of that to the garden district. one of the most fun times i ever had there was when my husband was in meetings all day and i jumped on the st. charles streetcar & took a self guided tour of the garden district. also, they have a fabulous art museum, great (pricey) antiquing on magazine street. new orleans is a great city to just walk. as much european as it is southern. just very unique.
when in florida, if you want beach time, plan on a few days in the "scenic hwy 30-a" area of the panhandle. the most gorgeous beaches in the world. seaside, watercolor, grayton beach, alys beach, rosemary beach are just a few of the communities to check out. plan on renting a bike and eating fabulous food.
disney/universal while in florida? it really is fun.
when in miami, try to get down to some of the keys.
if you have future college students, by all means tour each state's college campuses. as an alumnae of the university of alabama i have to say..VISIT TUSCALOOSA
! take a UA campus tour!
charleston and savannah are both fantastic towns. charleston in particular has an incredible food scene. both are wonderful, historic walking towns. if you have not been, take a guided tour. check out the outlying beach areas also. a side trip to ashville, nc would be wonderful.
good luck and have fun!!
