For Sunday, I have from around 09:00 - 20:00 to take in some sights.
So far, after lots of research, I've found that the Royal Palace, Cathedral Almudena, Plaza Mayor, Plaza Cibeles, Parque Del Retiro, Santiago Bernabeu tour and lunch at the Hard Rock Cafe are the most important and MUST see things to do in Madrid.
The plan at the moment is to first go to the stadium tour, then head to the Hard Rock Cafe, then walk to Plaza Cibeles and Parque Del Retiro. From there head to Plaza Mayor, then walk to the Cathedral and the Royal Palace and walk back to the Hotel Atlantico.
The problem I'm having is that I'm not too sure how long to spend on each place (except the tour of Bernabeu which will be 2 hours approx). And also, is there any MUST SEE places to visit that I haven't got on my itinerary?
Thanks for any advice! :)
