Just got back from Vegas and took a long, hot shower.  No, that is not me being influenced by Las Vegas' seedy underside; and it's not only because I was achy from the drive (although--man I forgot how long it is).  It is because I stayed at the Hilton and cannot vouch for the cleanliness of my surroundings.  Let me rewind.  When we arrived, I couldn't find much to complain about at first.  Check-in was quick and our room on the 25th floor was attractive to the eye.  The off-strip location was set away from the clutter without being isolated, due to its onsite monorail station.  But there were a few things that were bothersome.  Like the way the carpeting is so old in the casino that the smell of smoke just hangs on everything.  Like the fact that wi-fi was $13.99 a day (the reason I waited to write my review).  Like the fact that the room was lacking other common amenities, like a refrigerator and updated thermostat (although the former may be common in Vegas, due to the fact that they are trying to get you to spend money on going out to eat).  Or the fact that our sink backed up.  Or the irritating flourescent tubes right by the vanity mirror.  Or lame T.V. channel choices.  But still I was hedging on whether all these items earned the place a downgrade to a three--after all it *is* an older property.  But then my husband's cousin had to wait two hours for housekeeping to clean his room after a backed-up toilet situation and after calling twice for follow-up--they had to have different people come by for different purposes (one guy to plunge, one to mop, etc.).  Hubby actually had to walk down to the front desk so that one of their managers could talk to one of housekeeping's managers.  The three rating was confirmed.  And then my seven-year old (sure, it's a family destination) noticed the bitten-up pieces of cheese on our carpet in several parts of the carpet.  Ew.  That means they don't vacuum the carpet.  Definitely a downgrade to a two.  Sorry, but I expect basic cleanliness to give a hotel a three.  The lack of amenities is perhaps understandable given the low cost of the room; but the basics should never be overlooked.  Not my worst hotel experience (see my review of Naniloa Volcanoes Resort in Hawai'i)--but I expect much, much more from Hilton.
