October 2013 prices out at $391 R/T for the SFO-MCO-SFO nonstops on United metal - identical fare on every day in this general timeframe.
You could refare it right now and come out $50 per ticket ahead. As others have pointed out, you'd pay $150 to get the $200 credit to use on another itin. Fly somewhere else in the spring or summer or whatever.
SFO-MCO sometimes drops into the $250-300 R/T range for off-peak travel. A gamblin' man might go for it knowing that October seats will be part of a fare sale in the spring or summer, but I could certainly understand accepting $391 right now.
