Level Of Decency Depends On Your Location
Let me just start off by saying, this casino itself has mixed reviews. Never has it been one of the most popular or known for the highest level of security, but on the flip side it isn't poorly patrolled and there isn't a lot of violence or homelessness that floats through the parking lot regularly. But again there are a lot of mixed reviews, maybe it is just a casino thing.
With that being said, depending on where you are located at this spot you might have a peaceful night or you might be irritated by the sound of cars and the parking garage. The placement of this parking area is not terrible for getting in and out, though the spaces seem a bit narrow and I can't imagine people with a lot of slide outs being comfortable moving around their rig.
When I stayed in Vegas I came to check it out and it just seemed like of all the locations in Vegas this one was better than some but less great than others. You do have access to all the amenities of the casino itself when staying here, that is a nice addition to your stay, however some of those amenities are outdated.
I see this more as a place where retirees go to enjoy things than younger people so if you are wanting something a bit more lively in way of an updated pool or booming bar experience it isn't here. If you are wanting something more to focus on relaxing in the casino itself and playing games then it might work better.
