My kids had a karate tournament at the Riviera so we stayed there out of convenience.  When we first got to our room there was a USED bandaid in the planter.  I let front desk know and they said they would said housekeeping to take care of it...nope!  Also, our bathtub didn't drain, the furniture looks like it has 50 years of nicotine dripping off of it and the very best part - we were on a non smoking floor and our room smelled like a Willy Nelson concert.  Now my kids know what pot smells like.  Next year for the tournament we will be staying elsewhere.  The convenience isn't worth how grossed out I was by this hotel.
