Tickets for the 27th, 30th and 31st aren't available for pre-booking apparently. Does this mean it's basically first come first served those nights? Has anyone experienced this before? We were hoping to get tickets for the 31st but if it means competing with massive queues at the ticket booths for what could be hours then that's something we don't want to put the kids through. Think we'll look at 26th instead and be sure of getting tickets.
