There is no chance to see the shuttle up close. There is a 1 mile restricted zone around the pad, and the design of the pad is such that the service structure keeps you from seeing the shuttle when it is open or when it is closed.

Here is the link to NASA's various webcams. That is the best 99.9999999% of us will ever see.

Here is the link to the Flame Trench. It is one of the best sources of up to the minute launch news available.

Good luck, have a safe trip, and may the weather not scrub the launch.
