There isn't a way for a non-member to see availability for points reservations.
Once you pass ROFR (hope all goes well for you with that) and get entered into the system, you'll be able to book and see availability.
FWIW, it's going to be a long shot to get anything at BCV for this December. December is a tough reservation to get at the BCV if you can't book during the home resort priority period. The last time I looked for this December, the first two weeks were already booked up for studios and there was only a couple of scattered nights for a 1 bedroom. Not a whole lot better for the last 2 weeks.
I don't remember what it looked like for 2 bedrooms, but I doubt it was any better.
You may get lucky with a waitlist, but probably best to plan on staying at one of the larger resorts not near a park this time - SSR is the one most likely to be available.
The good news is that in the future, you shouldn't have trouble getting exactly what you want, when you want it, as long as you book when your 11 month window first opens.
Again - Good luck with ROFR!
