I just came back from staying at the MGM signature. This was during the weekend of the EDC, so I'm hoping it's not always like this. This pool is gross, no that word doesn't even come close to it. I was there when it first open on Monday afternoon, then went back up to my room that overlooked all pools at MGM and the water was actually brownish gray, all other pools were sparkling blue. I hope the pool was drained for the next day, I wasn't going to chance it though. Man eating bacteria anyone?
