Priority Club has one of the best promotions available for travel in Europe with the Stay 2 nights for the Price of 1 Night. This promotion takes rates down to as low as $50/night for some locations and even 5-star properties like the InterContinental Carlton in Cannes can be under $200/night using this promotion.
There is a discussion on FlyerTalk on whether these rates earn points or not. It seems that some members always get points and some members need to request points for the 2-for-1 stay, and some members are refused points for the 2-for-1 stay.
“No Points Given for “2 Nights for the Price of 1” is a good FlyerTalk thread to read regarding IHG 2-for-1 promotional rates in Europe. Regardless of the points situation , this 2-for-1 offer has some incredible deals for hotels in Europe. There are some InterContinental hotels participating in this offer.
One of the more interesting FlyerTalk posts in this thread states that back-to-back 2-for-1 reservations at the same hotel have been honored for an extended discount stay.
