I like the Cosmopolitan and the Aria especially the Sky Suites amazing rooms and views!If there is security agree to meet the lady at a certain location and go up together problem solved!I would prefer Aria or Cosmo over the Encore.
Good luck to you!

UMMMm I would pick Aria Suite & both hotels are easy to greet your lady downstairs ;-)

Have fun!

go with sumthing better

Cosmo was such bad experience that regardless of how much issues they fixed, really don't think will ever stay there.

anything with a great big hot tub in the middle of the room! I think Bally's used too, it seems the suites are nice, i like bellagio too. Top of the Flamingo is pretty cool, I'd like the Hefner suit at the palms...TheHotel is pretty nice if you're looking for a quiet place without a big price tag.
I haven't been to every hotel, but I have been to a lot of them. The MGM Signature is nice, the pool is salt water.

I've been to all and enjoy all...

Dealing with security has never been an issue for me (but I look innocent, hee hee)  As long as your lady leaves her clear heels and booty shorts at home, she should be fine.  You may have to go down and retrieve her at Encore, Aria or Cosmo but that's no biggie.  It's all in a day's work.  The one thing I recommend is you two meeting somewhere not directly in view of hotel security, i.e. not right in fornt of the elevators.

Good Luck!
