We're planning a visit to the Royal Palace for Friday May 12. Besides buying tickets online in advance (we will), are there any tips (what time, extra rooms to see, etc)?
Also, any insights to the audio guide? It seems to be available as a phone app that can be downloaded ahead of time, and also on a tablet that can be rented there. On one hand, the app's reviews at Google Play Store seem to be pretty bad -- is it really? On the other hand, does the tablet require a wait in line?
