Hmmm, yes, it looks like three days will be topping the addition of power to Endeavor, but they hope for additional work days in the future.

[Added all together, it’s a lot of stuff to get done in one mission – but thanks to an electrical boost from the space station, the 118 crew could have a little more time than most missions to get it all done. Endeavour will be the first to try out a new system designed to let the shuttle use electrical power from the station.

The extra juice will allow Endeavour to stay in space for an extended period of time while docked to the station. STS-118 currently is an 11-day mission with three spacewalks planned. Mission managers could add three more days and an additional spacewalk after the Station-Shuttle Power Transfer System (SSPTS) is activated and checked out.

Future missions could gain as many as six extra days once all the station’s solar arrays are installed and providing power to the SSPTS. This will become more important as the construction of the station continues.]

STS 118

Raoul, I love Florida, but the weather can either be predictable - scattered thunderstorms in summer afternoons or at it's worst, those hurricanes and occasional localized flooding after days of drought. Best months to be in Florida are during late Winter, late March, April and May. :)

I still think it's the best place for liftoffs.
