GHA Discovery, the loyalty program for Global Hotel Alliance (14 hotel brands with 300 hotels in 53 countries) is offering free, instant, mid-tier Platinum elite status at signup, using the above signup link.
Traditionally, platinum status is offered after you complete 10 stays at one of the chain's property.
Status is valid for two years from signup. Not the best of programs, but who am I to say no to free elite status?
Unknown expiry date.
