Turns out that fifthly comforter could have been mine for $110 ) Luckily we only live 1.5 hours from Mesquite, and we were able to give up on our little weekend get away and laugh about our disgusting experience all the way home.
There was also a sign that contained an inventory of every item in the room and what they would charge you if it went missing. There was even a sign in the bathroom warning us not to leave syringes laying around the room. We couldn't use the wall unit A/C because it blew in the urine smell from the outdoor carpet in the corridors. The bed had one sheet that barely even covered the top mattress, and then it was covered with an old fashioned fifthly comforter with the stitching coming out all over. Other reviews have mentioned that the beds are triple sheeted.
The mattress was so old you could feel the springs inside. The tub was dirty, the wood floors were dirty, and the walls and furniture were dusty. The building that contains the pet friendly rooms was completely foul and reeked of urine. For the first time ever, I checked into a hotel and immediately check back out.
