Planet Hollywood or Paris
Paris has Napoleons piano bar which is fun  
Planet Hollywood has the Miracle mile shops
Both have good restaurants and the rooms are clean and comfy.
The Ling is okay too
Have a great time where ever you stay

My opinion..

I like the Linq's remodeled rooms if you can get it free more spending money for other things
Another option is the Planet Hollywood.
Have fun!

The Flamigo

The Flamingo has remodeled rooms as well and they are nicer than the Linq. You also don't have to worry about security if you are going to hobby.

If you are offered a free room at Flamingo make sure its the NEW rooms
I had a new room there recently which was quite nice (I like Flamingo for photography due to their white bedheads)....and when I extended my stay they moved me to a different room... when I arrived to the second room it was an old room an I mean OLD.. it was so horrid I refused to stay in it.. packed my bags and left.

The linq has nice rooms although most Ive been in are quite small/ cramped with not much a view (if any.. some have no view just an opposing wall)
I should also say that every single time I have been to the Linq the hallways absolutely reeked of Marijuana.
While Im sure this is no concern to many, for those who dont smoke (or those like me who are extremely sensitive to marijuana - second hand smoke can stop my heart) it's worth a mention.
harrahs/Ballys.. a little outdated

personally I'd stay at PH

... my reason for not liking  Paris would not apply to you: They have cobblestone floors which makes walking in heels a nightmare :-P
