One potential "pro tip" - the second it hits 9am, open the above link in a Private/Incognito window - if it goes to the Waiting Room, close it. Keep doing that until it takes you directly into the queue.
It doesn't always work, but I've sometimes gotten shorter wait times doing that (usually via Ticketmaster or AXS rather than Disney, but they all use Queue-It). I'm suspicious that the Waiting Room to Queue transition happens on the user's end in the browser rather than on the website end, which could cause a delay.
