I'm the OP. Don't worry about a hijack.
BRPC really pissed me off last year and I didn't renew. I didn't brought students out there, because it is a non-commercial range, and I am not licensed in Boulder City. But I did a FREE class for the employees of a gun shop last year, and we went there to shoot. Not only did they kick me out for the day, even after acknowledging my intentions, but told me I had to go through orientation again (for purely punitive reasons). I never went back at all and did not renew my membership. It's their club. I may have been a little wrong, but they were A-HOLES about it.
And the range officer that day violated several NRA safety rules including sweeping both himself and me with his loaded unholstered sidearm. And it wasn't the first time. Some of their ROs have a bad reputation for safety, others for being dicks. But I'm the one that gets kicked out for the day. Mostly because I'm a nice guy that doesn't argue.
That said, I use to like their facility. My arrangement with Pro Gun Club allows me to bring students there and so I live with the disavantages, such as only one rifle bay that has to be shared. But they are growing constantly.
So to answer your question, you will not be able to shoot the day you join, unless you are the guest of another member, or you are using the Courtesy Range. Orientation is the first Saturday of every month (at least while they are still accepting applications (which is not all year).
