We were planning to visit Gibraltar but I couldn't drive our rental car into it. No Problem. It worked out great staying in the nearest Spanish town to Gibraltar, La Line de la Concepcion. It was about a 15 minute walk to the border and better yet, before entering Gibraltar there was a McDonald's that was open for breakfast: something not super common in this country that is not used to eggs and bacon in the morning. We didn't go to this town to see it, although I assume there are some things to see. But it is super convenient and makes it easy to see Gibraltar on a day trip.
