I received a free room offer from South Point last winter and took them up on it. The resort is nice with a bowling ally, movie theater, casino, bars and restaurant on-site. This is a locals casino so I wasn't expecting too much strip magic.
The resort rooms are nice with modern technology (lcd tv, alarm clock, etc). The bathrooms are a bit drab but are cleverly designed with bathtub and toilet separated from the sink room allowing use of the sink while someone else is showering. South Point gives out Bath and Body Works bath products which is a big plus!
The buffet was very average and did not justify the hour wait me and my friend had to endure. I would recommend the coffee shop over the buffet.
Staying at South Point and frequenting the strip was a bit of a chore as the hotel is pretty far. It is about a 10 - 15 min drive from the rest of the hotels on the strip. If you don't mind the distance, South Point offers great values, and a fun clean resort with low gaming minimums!
