3.75 stars. Value.
This is what the Riveria is about. Don't say it's a terrible place!
For a less than $75 per night reservation, it's pretty decent and comfortable and you're still on The Strip! Though the service at the Registration Desk may not be above par, you will be serviced but not particularly in a prompt and friendly manner. But again, who cares!
There was an electrical blackout during our stay at The Riveria, so the A/C and the electricity was out until the evening. So wait time wasn't great, but we did end up getting a clean room at the Monaco Towers. King-sized bed, TV, bathroom...all clean and good to go.
HOUSEKEEPING: We had the "do not disturb" sign during the day, but housekeeping still cleaned our room. I guess they don't pay attention to signs at these hotels!
PERKS: large parking lot and nice pool area.
