Old, dirty, unfriendly, unaccomadating. Never again, EVER! When we arrived for check in at 3:30 on Thursday we were told by a Michelle G, who checked us in, that there were were no longer any king size bedrooms available, which is what we had reserved. This left me to wonder whether the guests waiting in the gigantic and growing line behind me were going to be told the same thing and how pissed everyone was going to be, right? My husband asked how that was possible and the chick had the audacity to tell us that technically check is 3 but no one is guaranteed their room until 6 pm!! Seriously?! Then why isn't check in at 6?! That was ridiculous. She must've thought we were stupid or something. She treated us like second class citizens and this really disappointed me. Well after my husband refused to budge, she made a call and magically found a king size bedroom available. She took no responsibility, made no apologies and frankly looked mad at us for some reason! Talk about quality customer service, what a joke! Well she must have had some sort of beef with us because the room we got was awful! Ugly, drab, old and equivalent to a crappy holiday inn, even then that may be an insult to the holiday inn. The bathroom had mold and hard water stains, and small.  The furniture was chipped and dis colored and carpet was old. Mind you we're not pretentious or picky but even this was pretty bad for vegas! We called to complain but the hotel refused to take responsibility and said they'd call back to switch our rooms and never did. When we met up at our friend's room I noticed their room was bigger and newer and a tad better but even they weren't happy with their room. Never again will we make the mistake of staying here. The Monte Carlo claim that \""luxury should make you feel special no matter who you are\"" and that was a bunch of BS. I should've just stuck with the Mandalay bay or Luxor. Sorry for grammar and punctuation, I'm on my phone and mad!
