I don't like TI because they have security at the elevators that is very strict.  
Flamingo has hellacious parking.
Planet Hollywood has no parking so you have to park at the mall and walk over.
Excalibur is a hike to get around and complicated. Plus they sometimes have security at the elevators.

Monte Carlo is nice with big rooms and is easy to navigate from start to finish

Monte Carlo: no security at elevator, easy valet parking

But you'll have to ask for an upgraded room. Cause 1975 wants there furniture back and there keeping it hostage in some dingy rooms.

Excalibur - security (require key cards to gain access) at elevators
    Hard Rock - when i stayed there for avns in January, there were security at the Paradise Towwr enterance way requiring gsts to show their key cards and avn wristbands to gain access to rooms in the paradise tower. otherwise there was no security there asking to seed key cards there. Previous avns, they didnt have securityu at the elevators

Planet Hollywood or Monte Carlo.

I've had recent appointments at both with zero problemos!

Monte Carlo and Flamingo. I know that Treasure Island, and Excalibur have security. I am not sure about the others.

This year I've done both Bally's and Flamingo.  I barely noticed any security anywhere in either place.  Parking is way easier at Bally's if you are hosting. Get the front tower rooms at Bally's (Jubilee tower) its about 30 seconds from the Valet

Booked the Monte Carlo

Thanks to all who offered suggestions
