IHG Helsinki Stay 3 Pay 2 on Premium Rooms and Suites Through September 2026

IHG Hotels in Helsinki is offering an IHG One Rewards member rate that gives the third eligible night without an additional room charge when members book three nights in a Premium Room or Suite. The same structure extends to longer qualifying stays: six nights are charged as four. The official campaign says bookings can be made through September 15, 2026 for stays between May 25 and September 30, 2026, and normal IHG One Rewards points still apply. This is a members-only hotel promotion and availability depends on participating Helsinki properties, room types and dates. DealVorio records the offer as Stay 3 Pay 2 rather than inferring a universal percentage discount because nightly rates can differ. Travellers should sign in to IHG One Rewards and confirm that the campaign rate is selected before completing the reservation.
