Went by the field today....
The set up is at the KSC visitors center parking lot, unlike previous years when it was inside the visitors center. For those who haven't been to the Visitors Centor... it is a private attraction on NASA property. There are tours, IMAX movies, displays, etc. I expect you will have to pay this year to enter the attraction ($26 for adults), but I don't know this for sure. The FIRST event is free. See link below for info on the visitors center (including map)

The Pit area is an enclosed tent like Nationals. It will be air conditioned. The field is on a stage covered by a tent with three walls. Same set up as an outdoor Disney field but smaller. In fact, they use the same tent rental company. Bleachers are not protected from the weather. Alligators are in the ditches so stay clear of the water there (not kidding).
This is the first time it has been in the parking lot. I hope they let folks into the visitor's center for free. Otherwise it could make for a hot time and crowded pits.
