You'll be in a better position but not a perfect position. Especially when weather is an issue and cars are returned wet/dusty/muddy/whatever, it's considered reasonable to find damage during detailing that could have been missed at return because it was obscured.
Pictures of the car at return are one of the best ways to protect yourself, though. Make sure they're accurately timestamped and it's clear you're in the return area to remove all potential doubt about their veracity.
