but here's the BIG mystery...
. Free Night certificate(s) are valid at participating Hilton Family hotels including Hilton, Conrad, Coral by Hilton, Doubletree, Embassy Suites Hotels, Hampton Inn, Hampton Inn & Suites, Hilton Garden Inn and Homewood Suites by Hilton.
The go on about T&C's, but that just links to the HHonors T&C's, nothing to do with the promo... at least Hyatt is a bit clearer on which hotels (2 I believe) don't participate in the promo... I still stand by my Freddies quote "FFN is the best hotel promo bar none..."
