In 2018, the Loyalty Program will continue to honor Elite achievement via Qualifying Stays at participating SPG Brands that occur in 2018. Elite achievement via Qualifying Stays is only available until December 31, 2018 and will not be continued thereafter. Participating SPG Brands include: St. Regis® Hotels, The Luxury Collection®, W® Hotels, Sheraton®, Le Méridien®, Westin®, Tribute Portfolio®, Design Hotels TM, Four Points®, Aloft® Hotels and Element®. Members can earn Elite Status via Qualifying Stays under the requirements listed below:
● Gold Elite: 10 to 24 Qualifying Stays or 25 to 49 Qualifying Nights
● Platinum Elite: 25 or more Qualifying Stays or 50 to 74 Qualifying Nights
from their t&c ... interestingly no pltp or pltpa tiers ....

One could read this as saying that people with 100+ SPG only nights in 2018 (and not $20,000 spend) will have ambassador service through the remainder of 2018. For example, if you hit 100 nights in October (and didn't have an Ambassador earned the previous year), you would get Ambassador service for November and December of 2018 and probably January of 2019. I don't want to cause a panic or suggest that this is what Starriott means, but if we read the words that are written, this would be a reasonable interpretation.
Why doesn't Starriott have some extremely detail oriented person, perhaps a lawyer, who understands the program and can edit the T&Cs?
