Rather than specific time slots for drops, they just reopen reservations when they get caught up on current reservations. I suggest refreshing the page,
link is here, and keep refreshing periodically. I was able to get a reservation this way midday on Friday, whereas I usually have the worst luck with the timed drops lol.
Also, it appears to have taken a full hour this morning for all the Virtual Line reservations to be reserved... For me, a full hour at start of the day is much better than less than a second, so this still wins over Rise... (but of course, I prefer standby where I know I can just wait several hours in line and not have to be there early.)
EDIT: Just realized you said in a couple months. Who knows how it will be working, or if it'll even be in use, by then. But the above information is relevant to anyone visiting right now at least.
