I'm a loyal customer of the Venetian. Decided to try MGM out for the first time. Everything went perfectly at first, KA was great, buffet is good, but then house keeper was super rude to us in front of our KIDS, we came back to for a final check before we leave the room and was told we can't go to a certain part because she already cleaned it, like we're dirty or something.
I paid for extended check out at 3pm. Took the kids for lunch then came back to get our stuff to head to the air port at 2:15 and our key got deactivated. Took me 40 minutes standing in line to get it reactivated without any apology from the hotel, the WORST part is we ended up missing our flight back home because of that.
I missed work the next day and the kids were exhausted. Were impressed with MGM at first but the whole experience was ruined by the house keeper and the lack of communicating with customers. Like if there's a long line they don't really care, they talk about all kind of stuff with the people before you without knowing there's a long line behind them.
