My family will be touring in Sicily this September. I planned to spend two nights in/near Agrigento to see the ruins during the day, and then at night. We would be there September 21-23. It seems from reading other posts on this topic that you can no longer see the ruins lit up at night (after September 13th) unless you spend a lot of money for a private excursion (~ 900 Euros). Is this true? If it is, I'll probably take the second night and move it somewhere else in our trip. Thanks for your advice.
