We have three nights (three to four days)in Andalucia, not counting Seville and Granada. The original thought was renting a car for these four days and do the grand whirlwind tour of mainstream and hidden highlights.
By "mainstream" I mean Arcos, Jerez and Nerja.
By "hidden" I mean less accessible places such as beaches, caves, hikes, etc. (See subsequent post for some specific ideas.)
Any thoughts on rental car to allow visits to these less accessible places vs. just using buses to visit the few "biggies"
