It's a shame how inconsistent this program is.
Also, how far in advance are you guys booking stays with the upgrade certs? I've been trying to book for October, and the agent said she found the club upgrade rates (at 2 separate properties), but then every time she gave me the rate, it was the exact same as if I were to book the club room outright. Hoping she was just confused, but not sure if I am looking too early?
