That's an excellent reminder about the starting sale date for the Naviluz. Last Christmas we waited and couldn't snag tickets until Jan. 4, the next to the last night.

Cirque du Soleil will also be performing Luzia in Madrid until Jan. 22. One can purchase tickets here-

Here in Barcelona, we're also starting all the "xmas-related stuff" this week, from turning on the Xmas street lights to the most emblematic Xmas fair (https://www.firadesantallucia.cat/) and many other things. Keep in the loop with the City Hall's Xmas website: https://www.barcelona.cat/nadal/ca/nadal --which will be updated with 2022's activities within a few days.
