Imperial Palace- No Security
Harrah's- Security and very rude and ask for ID's however there is a secret back way up that isn't that hard to find and by passes security. Also if you see the lady before 8pm, she can access the elevators near the parking garage entrance. If she goes to the 4th floor, she can get to any tower 
The Flamingo- No Security
The Mirage- Security after 9pm or 10 but always sweet.
T.I.- Sometimes they have Security and other times not.
The Sahara- No Security
The Stratosphere- No Security
The Wynn- Security after 9pm but usually no problem.
The Palms- Security all the time. Sometimes they are accommodating and nice, other times rude and questionable.
The Rio- No Security for the most part but sometimes they do, usually nice but can be judgmental so best to meet downstairs.
The Orleans- Security but nice.
The Gold Coast- No Security to my knowledge.
Venetian- Security after 9pm on the 2nd story but requires key to enter and always security on main level.
The Palazzo- Security

GVR- No Security
Golden Nugget- Security after 9pm but sweet
Wild Wild West- No Security except patrolling the parking lots which is how you enter the room.
Palace Station- No security to my knowledge.
Trump Tower- Just opened but I haven't been there, sure there is security though.
Encore at the Wynn- Security no issues at all.
Palms Place- Key Access.
Red Rock- No security but key access only.
Aliante Station- Not to sure, I have yet to go there.
JW Marriot in Summerlin- No security.
Downtown hotels excluding the Golden Nugget I do not visit, so have no knowledge about and same for most casinos outside Las Vegas city limits.
So there it is. I hope this helps.

I frequently stay at the Renaissance on Paradise, north of Flamingo, and just south of the Hilton complex.
a non casino hotel, its less than 50 feet from the valrt to the elevator. No security, light traffic friendly staff.
I've had many visitors over the years, never an issue.
Plus they let me park my trike right there in front
