I just went on campus today to use the facilities. RSC is closed for the intersemester break (according to the website) so I went to Gregory. Our student IDs do get us past the guard on the way in. I can see why folks would line up to get a permanent locker. They have very few day use lockers, so you have to get a permanent one if you want to use a locker at the facilities. I'll have to check out the RSC to see which one I'll prefer to use.
The Gregory Gym looked respectable. It is a bit closer to the middle of campus, so I can understand that being the more frequented gym. It looks like they're both about the same distance from the Law School, though. It was around a 15 minute walk from the San Jacinto garage. That's almost enough to convince me to park a bike on campus just for commuting back and forth between the garage and gym.
