Complimentary suite upgrades for me this year was at an all time low without usage of the SNAs, of my 28 nights in Japan I only received 4 night upgrades (1 at Westin Tokyo,1 at Sheraton Hiroshima, 1 at Westin Kyoto). For Thailand, I got complimentary upgrades for Le Meridien Chiangmai for 3 nights. No upgrades thus far for the other 20 nights. Still have another 14 nights coming next week so will see how it will go.
