As most people, we were here for a convention, the annual NATCA convention - and it's no wonder it won't be held here again.  This is a very low quality-high priced, dated hotel, despite being bought by Caesars Entertainment.  \n\nThe casino ambiance is on-par with CircusCircus; low slung ceiling with years of cigarette smoke permeating everything, acres of frumpy people glued to video gambling.\n\nRio automatically charged us an $18 per-day 'resort fee' for a closed pool and uselessly weak WiFi.\n\nThe hike to the Strip turned out to be a hassle, as Rio's shuttle drops you off at either the rear parking area of Ballys or the back parking garage of Harrahs - & you could wait 20+ minutes on either end of these no-man-lands.\n\nThere's nothing interesting in the Rio's vincinity.  We hiked across glass-strewn abandoned parking lots to the Palms Hotel, for its movie theater --that's about it.\n\nThe mediocre buffet was $30-35 dinner --$17- (kids) $25 for breakfast.\n\nFor this, our Rio room was nearly $200/night.  A low-tiered Marriott.\n\nNever again.
