Rio rooms are nice and big, with a little living room area, although it's not actually a separate room from the bed. But the rooms are getting a little threadbare, like the property as a whole. Service was indifferent on one stay, small problems with the room were not addressed promptly. Harrah's has been neglecting the place. Consider Paris as an alternative, if you can get a comp. Rooms are much smaller, but really nicely appointed, although kind of fru-fru, just so you know. Much more heavily decorated than at the Rio. If you have to pay cash, Paris will probably cost more than Rio. Pools are good at both hotels, but the pool area at Rio is bigger. Buffets are good at both. Plenty of overpriced restaurants to choose from, wherever you go. Any specific questions?
