Dear Tim (and all,)
Many thanks for your insights and contributions -- 'very much appreciated now and in the future. We'll check out the smaller towns you mentioned.
Yes, we plan to NOT have the car in Granada - we mostly want to enjoy the city. As with most of our travels, we prefer mass transit when it makes sense, and don't mind taking a taxi when that's a reasonable thing to do. ...and we're good walkers/hikers...
Rick's books are our touchstones and first "go to" source for insights and planning any European trip. Over the years, they are consistently valuable for our tastes and preferences in travel. We have learned to make some adjustments for our personal preferences (e.g. we tend to spend longer in one place than some of his wide-ranging itineraries; tend to book lodgings at the mid-to-higher end of his recommendations) but Rick's books have been the foundation for many (all?) of our European travels. At each stop, the books do an excellent job of giving us a clear idea of what to expect, how to handle "the logistics" (e.g. great Alhambra tickets advice;) and whether it is worth a stop for our priorities and time -- but they ALWAYS have great suggestions and advice.
Work schedules and other issues have so far kept us from joining a "Rick tour," but I see one coming sooner or later.
That's why I get the sense that there is not enough "there, there" to make an actual stop IN Gibraltar for our interests, and as you say, the horse thing in Jerez doesn't hold much interest for us. In contrast, a great art museum (small to large;) historic settings and architecture; great walks/hikes; the right cultural performances (from free Church concerts to pricier theater/concerts); "high value" photography targets for the husband; a scenic place for a drink; etc. all get our attention. I LOVE it when the advice is honest, e.g. "the breakfast is great/skimpy..."
In addition: we tend to do a lot of research in other publications and sources. For example, the DK series provides very good maps of small streets in some key areas (yes, I know we can get maps locally at TI's, but again, I've always loved a good map for planning ahead. The photos are also good reconnaissance for a starting point for photography targets for the husband. We also check the more popular long-established travel book series (I don't know how touchy Rick is about mentioning competitors,) which we find useful, but supplementary to Rick's publications, downloads, etc. I try to buy good road maps in advance when I know that we'll rant a car.
An especial plug for Rick's advice: His is increasingly valuable when so much travel advice is getting a bit too homogenized, commercialized, or losing a real travel-as-enhancing-life-adventure focus. I subscribe to a number of travel publications, and am particularly put out by a re-positioning of one magazine. Its October issue had an over-hyped CELEBRITY on the cover (!!??!) when they could have had a photo of an interesting place to visit. I'm sure that a part of the repositioning has to do with advertising revenue and targeting a younger customer profile, but really -a lot more of the ads and editorial are from luxury clothing/car/etc. brands rather than travel brands.
