it’s only “wide open” if you’re looking past Labor Day weekend. That weekend there is nothing but crumbs and times were literally vanishing faster than I could click on them.
Was able to book for late October, lots of availability but even after I finished and opened a new window I was able to go right back in to book again (I didn't) so it definitely remembers you.
I think something is wrong with the queue, I was able to make 2 reservations under the same queue and for the same day. That shouldn't be happening lol
