Do I really have to give this one star?  Where to begin?  First tip off that our stay was going to be less than great, less than good, less than bad...the check in line.  Over an hour wait to check in to an overbooked hotel, it's like they expect for some of the guests to go to their room and imediately check out.  Reserved an upgraded non smoking room, received a standard smoking rooom.  Went to the front desk and asked to be moved to the room that was reserved, no can do, sold out.  After an aweful night sleep, uncomfortable bed, fighting in the halls and the smell of MJ all through out, we started shopping for another hotel.  Called the front desk and spoke to a manager, told the manager that we would be checking out at noon and requesting a refund if not moved to a better, quieter room.  Almost completely reserved at the Rio when the manager calls and says a new room will be available in 2 hours.  Do we risk it?  One in our party wanted to just make do and so we stayed.  \nThe lobby and casino are straight up stressful.  Packed elevators (took the stairs a lot), long waits, and inebriated 21 year olds every where.  Not enough security to handle that many people, although I did observe one security evicting a prostitute that was trying to talk her way into an elevator with an older man.  \nSpend the extra $$ and go next door to Flamingo or Harrah's, you will be thankful you did.
