'hailstorm' at Flyertalk has discovered a great BRG opportunity for the Park Hyatt Tokyo. The hotel runs about $600/night usually but shows rates of $334 before cancellation now at Orbitz. The example below is for June 10th (one night) but more dates should be available.
To take advantage of this deal you will need to file a successful Hyatt BRG.
This claim looks very good and should be approved.
I went to see (but did not stay at) the Park Hyatt Tokyo in 2012 and was thoroughly impressed.
