I recently stayed at the South Point for 2 nights. Overall a great experience!! The rooms were clean, well appointed and the casino was huge and not very smokey. They had all the games that you would normally find at the casinos on the strip but without the pretentious and or intoxicated crowd. I agree with the other reviewers that because of the distance from the strip you don't really get the full Vegas experience but South Point does offer a shuttle service to the strip for $8/day. They run on the hour every hour until 2 am I think.
During our most recent trip they provided coupon books that offered free well drinks, 50% off the buffet and a free dessert at a few of their in house restaurants as well as other offers. We tried the seafood buffet dinner and they had the usual + all you can eat crab legs, with the coupon it was $9/person...not bad at all. Also tried the Coronado cafe and Don Vito's Italian. Great service at both restaurants. Good food and reasonably priced.
Ample parking and quick access to the hotel were 2 other positives.
I would recommend this hotel/casino to anyone that would like to have Vegas fun on a budget!!
