The Rio is a classic hotel and I always love to stop by and check out the interior. It does remind me of Carnival! I'm super bummed that they don't do their free Carnival show anymore so there really is no point in venturing off strip to see this older casino.
The buffet is my mom's favorite so maybe the buffet is worth coming to try? I don't know... a lot of other new casinos on the strip are a lot more glamorous and have better buffets.
3 stars for A-OK hotel and casino because it has stayed a float all these years!
