LAS VEGAS (KLAS) —  The reservations part of MGM Resorts International Las Vegas website is still not online more than one week after the resort experienced a cyber attack that crippled the resort’s computer systems and caused problems with reservations and gaming machines.

The resort’s web page states, “Online hotel reservations are currently unavailable” and says any reservations booked between Sept. 13-24, 2023, can be canceled or changed without fees. This offer was set to end on Sept. 17 but was extended another week. Reservations can be booked by calling the resort or a third-party site.

Guests can book shows and restaurant reservations through the website or the MGM’s app.

Some guests who spoke with 8 News Now as they checked from MGM property Excalibur said they still have to wait for an attendant to cash out slot machines or go to the cashier’s cage to redeem winning tickets.

“Once you cashed out you had to press the service button and wait,” Bryan Padilla said. “It was irritating to wait 20 minutes or so for people to find you.”

While guests in line at the Excalibur said they had to wait a half-hour or more to check into their rooms.

“I think we waited for 40 to 45 minutes in line to check in,” Lizbeth Garcia said. ” Other than that, everything was fine.”

Meanwhile, Thomas Duffrene told 8 News Now he stayed at the New York – New York and that the check-in process was quick. He said he played table games and took his gaming chips to a cashier.

A sign tells customers there are still “unforeseen difficulties” at the Excalibur on Sept. 18, 2023. (KLAS)

MGM Resorts International has around a dozen Las Vegas properties.

Last week, a group known as BlackCat took credit for the attack, which began impacting the resort on Sunday, Sept. 10.

MGM Resorts International has not released any additional information since Thursday, when Bill Hornbuckle, CEO of MGM Resorts, thanked guests and employees for their patience.

The FBI is investigating the incident.
