Yeah, I've only ever done it in cash. I'll normally head to the registration place late at night the day before the tourney I want, or just register them all at once once I get there, it's down at the end of the Rio in the hallway between the conference rooms. I think you can register via internet or credit card/wire but I've never done it that way. They also have satellites sitngo's that you can win lammers that are basically just tourney coupons that work like cash. People will buy them at nearly face value if not full face value if you want to play those to grind out some shit before dinner or for fun.

The cash games at WSOP are NUTS. Like super crazy. I played a 1/2 PLO game and average stack was like 2k, some guy had 8k on table.

Their daily tourneys the $265/$165's get like thousands of people and sometimes are like $70k-$80k+ to first but they're long tournaments. Run em every day though. If I bust something or am bored I'll register the 4PM $165 (may be a diff price now) and play it that night. Like 25k chips, 30 minute levels, decent structure, easy fields.
