Got there a little before 8, didn't even get a voucher (before the Rock of Despair or whatever it's called). I guess there were fewer seats available to average Joes today (or at least to the people in line) because it was Manhattan's day and there were a lot of friends of the production who'd reserved tickets in advance.
Stuck around for the standby line, ended up being around 20th for that (behind the 38 vouchers who showed up and could claim 76 tickets). The cutoff for the standby line was a few people behind me, but I ended up making it in after the opening number—and to great seats, too!
Public staff were recommending people arrive around 6 if they really want a ticket. Also, no surprise here, but they're expecting this weekend, and all weekends, to be particularly insane.
ETA: There is wifi if you're close enough to the Delacorte—but unless you're SUPER early, you probably won't be close enough to get it.
