Treasure Island e.g. but also other hotels offer coupons and freebies if you book your hotel room directly with their website. Hotels have various promotions available which give you some extras. Keep an eye on http://www.vegas-hotels-online.com - it has the latest promotions from many Las Vegas hotels available.
Right now NY NY is offering $39 weekend rooms . . . plus they give you a coupon for 2 free drinks and 1/2 off one meal inside the hotel.You really cant beat that. Plus if you gamble you are almost guaranteed to get free room offers in the mail for your next trip (just use your players card)
All hotels offer a little something but not freebies, just discounts. That is unless you are a very repeat customer or a known whale, high gambler
On the strip probably Sahara Hotel and Casino
