The final number of seats is around 3,000, said Paul Edwards, the general manager of the convention center.
The prime seats are assigned, with candidates each getting a row for their supporters.
The Sun News got a sneak peak this morning.
Up front, S.C. Republican Party Chairman Katon Dawson has two prime seats, for him and his wife, and next to them are two seats for Gov. Mark Sanford.
The candidates' seats are divided, three rows on each side of the stage.
On stage left, there's a row for Sen. John McCain, a row for former Gov. Mitt Romney and then a row for former Sen. Fred Thompson. On stage right, there's a row for former New York Mayor Rudy Giuliani, one for former Gov. Mike Huckabee and finally a row for Rep. Ron Paul.
