Holly,
So many fantastic Hotels but if you want a little more funky and lots of decor.  
 Its's a gem,
 I took pics there years ago.
 and It has a topless optional pool,
 Not bad rates at all,
 Groupon has a fantastic price right now.
 Happy Hunting Sweetie

January

...as a girlfriend and I have a shoot scheduled soon and have spent Countless hours searching online this last week.

My top 3 favorite were...
1) Hot pink suite at the Palms
2) Skyline Terrace suit at MGM
3) Aria corner suite. (more for lighting then decor)

We chose the Skyline Terrace suite at the MGM.

I stay at the Cosmopolitan when I come to town.  As I see ladies post photos on the photo board or see what they share on Twitter an others, I frequently see the Cosmo balcony and furniture, unique bathroom wallpaper, and room set-up from the suites and corner rooms.  One trip I would love to offer the room for a shoot.  Would be fun to see.

Wynn, Encore are nice rooms,
Palazzo and Venetian have large rooms - with nice sitting area

Cosmo, is always one of the better one with its sitting area, nice bathrooms and "ohh" that balcony

The Signature suites at MGM are also nice option.

Vdara and Aria corner suites are nice.

Lower room costs: SLS are nice, PH (new Ultra hop room),  
IF you do not mind the drive...JW Marriott (golf course view)
