This reminds me of the first Vegan Festival in Brisbane Australia in 2015 in terms of somewhat poor organisation. In Brisbane, the venue was way too small for the numbers, they made everyone wait ages to get in despite advertising the opening time, the food lines were too long and then they ran out of food. It was a big mess basically and people really vented their frustrations to the organisers on social media. That said, the speakers there were really good and if you could get food it was also pretty good. I wasn't in Australia last year so I'm not sure if it improved.

Hopefully one day I'll make it to one of the successful, well organised events!
