I haven't been in a few years, so things might have changed, but last time I was there, there was one or two banks of lockers (i think they were all the way at the end) that did not require a wristband and could be paid in cash. I always used those lockers so that our group could simply share the pin\colour combination... is this still the case?
I don't even know why i'm bothering to reply to this, but seriously Push - you get unlimited entry to three parks for ~$100 a year. You want the parks to build more attractions you like, but at $33 a year per park (less now that PC is included too) how much do you think they profit from the free admission? Your self-entitled pompous bullshit is disturbing.
Each park used to cost more than $100 a year for annual membership. IIRC when I first came to Brisbane they were about $299 each. Why do you think your cut-price, anyone can (and probably does) membership entitles you to free use?
Not everyone needs a locker. Some people visit the parks with a non-riding friend who can mind your stuff. If it's that bad, go into the park with a pair of shorts that has a velcro pocket, a dry-pouch for your membership card (that goes into the pocket) and a towel and thongs. leave the thongs and towel near the entrance to the ride you're going on (few people would steal someone's thongs or towel) and then you solve both the locker problem, and the burning path problem.
I suppose next you'll expect VIP seating at shows, and a free lunch.
