Bought tickets for galleria, following v frustrating process. Had registered at home on line at least 3 times and no acknowledgement. Emailed 3 times... no resolution... called prepared to pay for seats on line.
Called to La Scala pm On arrival in Milan and registered again which was checked by man in sales shop. Queued for number at 17.30 and went to buy tickets at 18.00 to be told that I WAS NOT REGISTERED. Went to do again at ticket sellers insistence to be told I was registered. Eventually bought 2 tickets. While they are incredible value, they do say limited view. However there was no view whatsoever. Dashed to next floor just before show started and got 2 seats with a limited view. Very frustrating and took up a huge amount of time.
