There will be a staffed sight-in area available beginning Thursday at 1 pm.
Registration will be at the range on Thursday from 1-5pm and then at the match hotel from 7-9pm.
The charts will give you a general idea as to pattern. But you will need to shoot them through your gun and see what the spread looks like at different distances.
You shouldn't have a problem with any regular passenger car, just don't bring out anything that's lowered. Save "The Fast and the Furious" for the shooting.
The range is about a 20 minute drive from the strip and the match hotel.
The Riviera is one of the older hotels on the strip, it has been remodeled but it still isn't as nice as some of the newer ones. On your 1-5 scale, I would give it a 2 - 2.5
