You have ample opportunities for a "little road trip" using Orlando and/or Las Vegas as a base without the long slog across I-10.
South Florida offers everything from the Kennedy Space Center to South Beach to Everglades National Park to The Keys and Key West plus a half hundred more depending on your tastes.
Las Vegas offers a dozen or more spectacular national and state parks within a day's drive.
I recommend Google, Rand-MacNally, and AAA as resources to plan a "little road trip."
