Though Dreamworld's had the closest thing to quiet zones in comparison to Movie World w/ their Kickback Cove & Corroboree areas (though, I guess Doomsday's section could be considered a quiet zone now that nothing's open), this is genuinely a great idea and I really hope that the other parks follow suit. I've been wanting to have a nice place to level myself while at the parks many times, and have mostly just resorted to going on Sky Voyager or Justice League if there's a short queue, or the aforementioned areas of the parks if there's not a lot of wandering guests (headphones & sunglasses also help with both scenarios), but this is gonna be a huge help especially when the park's feeling packed.
