Sounds like a tough sell from your description.
You're essentially selling a crash pad idea, without the flexibility of a commuter having a place to hang out between days/trips/reserve.
I lived in Houston and was based in Dallas and needed a place to sleep when it was an early show and I drove up from Houston the night before, I got a hotel and hotels in Dallas are cheap and I suppose they are cheap in Houston too for crews. Also, when I finished a trip and had days off ahead of me, I was on the road back home. No way would I sacrifice a night in my own bed and stay in a hotel another night that I didn't need to.
I'm trying to just give you my perspective based on what I thought when I was doing exactly what it seems you are targeting. To make this a viable option, you need to rent out the rooms to commuting crews who need a crash pad and not try and go after the few of us that drive to base and hope we need a room once in base. We are/were few and far between.
