Apparently IHG’s Priority Club has two different promotions running for stays/nights that are mutually exclusive. The other one is based on the number of nights stayed and the other one is based on number of stays.
These are the lowest nights/stays to earn the maximum number of points. There are other variations of this offer as well. The best offer is the 10 stays for 15K Priority Club points if most of your stays are no more than a night. Alternatively, you can sign up for the nights based promotion.
You can register for these promotions at priorityclub.com/register. Please note that you can only choose one of these offers and it cannot be changed later. This promotion starts on April 1st and is valid until June 30th, 2012.
