roma pass官网上关于“圣天使城堡”最新信息的疑

在Roma pass官网首页上看到这个
Please note:the Castel Sant'Angelo PIT (tourist info point) closes on April 30, 2015 and will be replaced by the Auditorium PIT. All cards purchased online due to be collected at the Castel Sant'Angelo PIT will be available at the Auditorium PIT (on Via della Conciliazione 3, only 100 mts far from the other PIT)这个是什么意思啊，是4月30日这天roma pass不能在圣天使城堡用，还是4月30日以后都不能用了，还是别的只是改变PIT (tourist info point) 位置的问题啊，有没有高手指教下，急求，马上就要出发了
