would like some info on some of the best for hobbying and easiest (little or no security) to access for providers? It also has to be a nice place with nice accomidations. My choice is the Mandarin Oriental.

Your choice of Mandarin Oriental has security from what I can last remember.  
Some places you can try, Paris, Planet Hollywood, Monte Carlo, MGM.  Now of course all this is subject to change who knows how they decide to have security or not.  But if its a huge event that weekend sometimes all of the casinos will have security to control the crowds.

Just my 2 cents.

I'll be staying at PH in a few weeks, so I had asked the same question

So these are hotels to avoid because of LE?

Oh no, the OP had inquired about hotels that don't check key cards on the way up the elevators.   The list I posted are ones that others have said don't required key cards.
