Just got back from the Rio - Excellent experience.  Great room - very spacious.  Terrific bed! - very clean.  The shuttle service is sooo convenient.  Very friendly staff.  Fridge works very well.  So very comfortable - good security.  Found two places to eat that were marvelous.  Hash House  A Go Go - zagat rated - and a steak and hamburger restaurant (can't think of the name). Neither expensive.  Only complaint  way too much food.  Share the order.  Really don't like monstrous amounts of food - such a waste - for me anyway.  But it is delicious - especially the hamburgers! - Terrific breakfasts.
