If you do get to Ljubljana, try the Human Fish beer. It's their idea of a bitter. It's, interesting. Failing that, there is a nice lager there called Lasko (pronounced Lashko). You can get that anywhere. There is an Irish pub (isnt there one everywhere?) which has a good selection of UK beers. The zoo is also rather lovely. It's less like a zoo, and more like a walk in the park with added giraffes. They also occasionally run a steam train from Jesenice, near Bled, to Gorica, which is well worth doing. They have entertainment at some of the stations, and you get to meet Archduke Franz Ferdinand (who seems remarkably healthy, all things considered). The scenery is stunning. We did a variation on this which included a coach trip. That also included a lovely village called Smartno, a visit to a vineyard, and a fantastic meal. The whole trip takes a day, but is worth doing. One very important thing about Ljubljana - never hail a cab! They charge an insane rate for that. If you want a cab, book it by phone. Even call your hotel and get them to do it. The price difference is roughly threefold, and they will not listen if you end up with a bill you cannot pay. We've not done the Croatian coast, but we've driven through the country a few times. Zagreb seems a nice place, but we've never really had the chance to have a proper look at it.
