At the Excalibur Hotel & Casino in Las Vegas, room rates are primarily based on double occupancy, meaning the price is the same for one or two people. However, in 2026, Excalibur—like most MGM Collection properties—charges an "Extra Guest Fee" for a third or fourth adult (aged 18+) staying in the same room. This fee is typically around $35 to $45 per person, per night, plus tax. Children under the age of 18 usually stay for free when using existing bedding. It is a common misconception that you can "sneak" extra people in; however, you will need extra room keys to access the elevators, and the hotel uses these keys to track guest counts. Additionally, the mandatory Resort Fee (currently around $40 per room, per night) is charged per room, not per person. If you are booking a suite or a larger "Royal Room," the occupancy limits may be higher, but the "per-person" surcharge for adults beyond the first two is a standard industry practice designed to cover the increased utility and housekeeping costs associated with more guests in a single unit.
