USPC Act 1 Super Satellite

[StregaChess]

Sorry if this is lame but I only play online.
I saw that the USPC is coming up and I'm not that far from AC.
I don't see a lot of detail on the site so wondering if anyone could do a run down of the Satellite structures and typical number of entries etc. A lot of them mention Act 1, and a few Act 2's so I'm guessing 1 gets you into 2 and that's it. 2 gets you into the main event.
(dying to get a few days away from diaper duty, say prayer for me..)
Thanks in advance.....
