To the question of where we've used the cert.:
2018: Indigo Rome
2017: Holiday Inn 6th Ave.-Chelsea (probably could have gotten a better NYC property, but combined it with a free night at the Hilton on the same block)
2016: Indigo Rome
2015: Mark Hopkins San Francisco
2014: Hotel de la Ville Rome (since closed)
2013: IC Boston
2012: Hotel de la Ville Rome
