***************************(my daughter)& I booked back to back complementary nights at **** through MGM ***************************** reservation was 3/24-3/25(MGM rewards) & Maribels was on 3/25-3/26(myVegas comp). We were offered to upgrade to ********* for $50/night. We agreed.On 3/25 we inquired about extending our stay 1 night. A man called our room(#*****)at 8am on 3/26 to say they can extend the same room at a rate of $260. I told him we will call back asap if we can change our flights. We paid to change our ************ daughter called the front desk back.The woman told us its taken care of but we have to get new keys. About 20 min later we received a call from *******, who said the actual rate is $700+. We would not have extended if the room was $700+. She said the guy misquoted & theres nothing she could do.My son in law then spoke w/her to explain the problem. She said as a courtesy she will reduce it to $500 & send up new keys. This is a disgusting practice, bait & switch. **** called me & said $260,it was confirmed AGAIN when we called back, we already paid our flights & then they turn around & tell us the rate is TRIPLE. So I called MGM Rewards to see if I can use a comp night for 3/26 since I had offers. I spoke w/******(MGM rewards) who, from what I understood, said yes & I even have up to 3 *********** can stay in the same room(*****)& just to go down to the front desk . I took my son in ******** BOTH confirmed w/Sky suites front desk woman(*********,w/long straight black hair working on 3/26 around 9:30am) that we originally spoke w/*******, but I (*******) was able to get a comp night instead.It took her a little bit to research, but she said she found the notes, gave us new keys, & said we ******** the resort fee. Later, our keys didnt work, and a ******* brought up new keys. We go to check out 3/27 & its charging $500 to my ************** everyones saying theres no notes?! Replay video of front desk interaction on 3/26 & fix this mess.
