Fetch your suitcase, walk out of Barcelona Airport (BLA-General Jose Antonio Anzoategui Intl.), and collect your rental car. Which one you slide into depends on where you plan to go. If you’ll be mainly driving in downtown Barcelona, around 1 mile from the terminal, select something zippy and small. A compact car that’s easy to operate will suit those bustling city streets. But with a wealth of things to see, like the picturesque coral reefs of the surrounding area, you’ll probably be racking up a few miles. A bigger vehicle, like an SUV or a full-size car, will make longer road trips more comfortable.
