I've search online, but cannot find the answer to this question. The dates for this event are 27 Sept to 14 October, tickets go on sale 1 February 2018. Is the show the same each date? If not, how does one know what date to choose? Opening night, I assume is the popular event date. Coming from California, so I need to purchase air tickets and want to be ready to purchase WOW tickets when they go on sale. Thanks.
