I noticed yesterday that you can now register online for WSOP events. There is also a map on the WSOP website of the layout for the tournament.
As in years past you still have to get verified in person to get your seat card so you'd better get there early.

I registered for the Reunion Day 1c (I think) on June 4th. (I know, I know! But I couldn't help it!)
I plan to get there a day early and go get verified on the night of June 3rd.
