I'm really torn on what rating to give this place. First off, we stayed here on a Friday, which happened to be the first night of EDC. I expected Vegas to be busy so I figured there would be wait checking out. But unfortunately, their computers were down or something on that day, and check in took over 2 hours!! I know this is isn't there fault and they did everything they could to remedy the situation (free drinks, snacks, etc.) So my issue isn't really this. My issue is more about the aftermath of the day (i.e. my credit card bill) \n\nBecause of the 2 hour wait, my friend was able to convince the front desk lady to give him a bit of a discount. She supposedly gave us $100 dollars off. Sounds awesome right? Well not when you end up being overcharged $82 on your credit card bill 5 days later. So when we checked out of the hotel, the computers must have still be down because we couldn't check out through our TV and there was no way in hell I was going to go wait in line for another 1 or 2 just to check out. Instead, I called down to the front desk, waited on hold for about 20 minutes and finally checked out. Since I did this, I wasn't able to see my bill because they were going to email it to me. Well the last thing I want to do in Vegas is check my email and worry about work so I waited until I got home to check my bill.\n\nWe were given the $100 discount but they then charged us $30 for a late check out fee, even though we specifically booked through a promotion saying we are supposed to check out at 4:00 p.m. (this was also confirmed on the day of check in) So basically we were only overcharged $30. No big deal, I thought it would be a quick fix. \n\nI call Mandalay Bay to get a credit back on my card. Apparently I have to talk to the accounting department. I end up on hold for AN HOUR!!! No one picks up. Are you kidding me? An hour?? I then decide to email the accounting department. I have not gotten a response to date.  I then call the accounting department again two days later. Another ridiculously long hold. I then call the  front desk and explain to them that there is a problem on my bill and she says she'll try to fix it for me. Big mistake. She ended up correctly charging my credit card but then she charged my friends card $82!! (his card was on file because he checked in and used his card for incidentals) I have no idea where that amount came from and they did not have permission to charge his card. Now he can't get a hold of the accounting department to get a credit on his card. \n\nIf this didn't happen, I would have given the hotel 4 stars. Rooms were clean. Service was decent. Good restaurant options. Awesome pool. But giving me a discount and then overcharging my card and my friends card? Unacceptable.
