I am going to vegas in feb. an would like to find some nice company.Do I need to book an appointment or can I just go down stairs and pick one out?Iam not familiar with how things work there.

In LV, you can do anything you want.  An appointment would be more reliable but not 100%.  Going downstairs to the bar depends on where you are staying but generally there's a pretty good vareity of ladies from about 11-2 or later on weekends.

Is one casino better or hotterthan another?I will be at the stratus.

other hotels for finding girls....like Manadalay Bay or The Venetian.  Then you've got the problem of the extra time and probably funds to get them back to your hotel.
    I've always prefered, and would suggest to you, to look thru reviews and web links here, to find a well reviewed Indie, that does what you want (might not be full service, or as complete as you want, with a bar girl) e-mail/call to discuss possibilities, and book ahead.  Have someone, or more, to look forward to.......and, know what you're going to get.
Good Luck!

because then I would have also mentioned that $$ in Vegas just won't really buy much......unless,maybe you want to hit the streets around the Strat..........and, that is NOT recommended!!!!  Could possibly lead to different accomodations that would not be enjoyed.
Great women here!! Just plan on spending more.

Not one to normally give suggestions but Vegas clearly has plenty of beautiful women.  If you like asians (I love em) would be to contact www.asianjackie.com.  To me this woman has it all.  Absolutely beautiful and 12 pages of great reviews.  Her last review was on 12/06.  If I ever get to Vegas again, she would be the first one I would call.  Just my 2 cents worth.  She is an independent and I'll guarantee all her review can't be wrong.
