Confirmed that they do not take the senior/access pass for a camping discount like Willow Beach, but they do have a 10% discount for Good Sam, Military, and First Responders!

The senior/access pass will get you through the NP gate that leads to Lake Mead RV Village. However, Lake Mead RV Village is a private campground, so you don't get the half-off pass price.

No...This is a privately owned RV/trailer park with lots of permanent residents.

I was unable to reserve via Recreation.gov. I had to call and I did not get the Senior Pass discount.

they did not in 2019 but i haven't been there since then.
