Janet told us on 5/18 that SMART would not be staying at the FAMCAMP for BF 2013. She said arrival two-three days before the event would result in a site. That being said, the suggestion to stay at Balloon Fiesta RV parking is absolutely right. Being immersed in the experience is unbeatable. There is still plenty of freedom to get in and out for shopping, sightseeing, etc.
The Eubanks Gate is the closest to FAMCAMP and doesn't have any size issues.
