Why queue for hours when you can go online and buy skip-the-line entry for Alcázar? I’m not usually a fan of tours but I’d recommend a small group guided tour of this fascinating place. Our guide seemed simultaneously proud yet embarrassed of the Palace’s role as the planning base for Spain’s colonising expeditions of the Americas. We toured for 1.5 hours then wandered the grounds ourselves. It was busy with tourists in the Palace but peaceful in the vast gardens. Just beware of the hazards, I’ve never seen so many near misses as people tripped over shallow steps and small fountains while taking photos.
