We went last year. I guess it depends on where you stay as there are 4 different lots with varying amounts of room. We stayed at the VIP East lot, we didn't have a clue what to expect when we made the reservation but were pleased with our choice, great view of the grounds for watching early in the morning and during the lift offs. We got up early every morning, what a site.
We actually stayed at the Sandia Casino the night before, this area was crammed tight with campers parked any way they could. Made it difficult getting around. My wife drove the toad over separate to the balloon fesival which made it a lot easier to park. We got there right at noon and ended up getting a front row site that overlooked the grounds.
We kept the toad unhitched until we pulled out of our spot and then hooked up the toad.
After our stay at the balloon festival we made tour of norther NM, visiting Santa Fee, Las Alamos, then to Taos. We then stopped back at the Sandia Casino to spend a couple more days there. Then headed south to Los Cruses for 4 days.
