Camping Access Question

Does anyone know if we’ll be able to access a campground other than our own? My partner and I inadvertently bought 3-day pass & camping, but with one camping at LaVerne and the other onsite. Will still only set up one site in each campground, but would like to be able to hang with each other at one or the other sites.

I’m not sure but I have an extra LaVerne camping pass that I’m happy to gift you if you want it.

You can visit other campgrounds, but the only place you can set up your campsite is the campground that you purchased.

As a follow up question to this… We have LVJ car camping passes…
Once we are camped in place can we drive in/out of LVJ over the course of the weekend?
Or is the car not able to be driven in/out?
Thanks!
