Madrid offers all the components of a memorable Spanish vacation. Cultural opportunities are endless, with some of the world’s best art museums and palaces on full display in all their ornate splendor. Make these kid-friendly with a guided tour to bring the history and technique alive, and then relax and play in one of Madrid’s many parks, like beautiful Retiro Park. People-watching in the colorful plazas is fun for everyone; children love these big, open expanses for running. Luxury hotels that are still kid-friendly make a family stay here not just comfortable, but a true indulgence.
