Goin to Vegas since I was a young in, and staying at the Rio forever...
When My siblings and I were all old enough we learned early that drinks at Rio can be expensive, so to counter the cost we
1. Bring a bottle/12 pack to the room.
2. Go across the parking lot to the GC for drinks and to rock out to the live band they have.
They always have an Asian band rock-in out to top 40/ salsa and always seems to be a crew of the Asian Persuasion dancing the electric slide to every song. I'm not mocking them, its a damn good time. The drinks are regulated now, not as strong as they used to be and the Prices are good. Liquor store on site and prioces not marked up too crazy there either.
Our last few trips to Vegas we stayed here, the rooms are smallish but newly refurbished. We'll Likely stay here again and they're sending me offers like I'm a big shot...BAALLIINNN!!!
