No, you read it totally wrong. The convention runs from Friday through Monday for the general public (4 days). Members of the FC get in one day early, Thursday. The $110 is also the early registration price. The at the door price will be $125 and you probably won't be let in Thursday.

Think of that Thursday as the equivalent to Comic-Con's Wednesday preview night. You only get in that night if you've preregistered a 4 day badge. This is the same concept. The difference is that CIV is running Friday through Monday (Memorial day) with the 5th day being Thursday.
