Hummingbear,
The DEN Training Center has security homies that require proper ID's and other stuff to keep the riff-raff out. You need at the very least a UAL escort and temp security badge to wander around. Fleet Captains and others that have any pull are very busy and hard to nail down unless your "escort" knows somebody. TK is not really a place where you can drop a resume on someone. Sorry for the buzzkill but facts is facts.
