Yes, IHG One Rewards members can receive free room upgrades, but this benefit is strictly reserved for those in the higher elite tiers. As of 2026, members with Platinum Elite and Diamond Elite status are eligible for "complimentary room upgrades" at check-in, subject to availability. These upgrades are typically to a "preferred" room, which might mean a higher floor, a better view, or a slightly larger room layout, but they do not always guarantee a move to a full suite. Diamond members generally receive the highest priority for these perks. For those in the lower "Silver" or "Gold" tiers, upgrades are not a standard benefit, though they may still receive "preferred" room placement if the hotel is not full. It is important to note that upgrades are at the discretion of the individual hotel and are often excluded at certain brands like IHG Army Hotels or InterContinental Alliance Resorts. To increase your chances, it is always recommended to book directly through the IHG website and politely confirm your status during the check-in process at the front desk.
