The flash sale indicates that the rate discount should be 40% at this property, but the rates were only discounted by 25% for the dates I was looking at.
If you managed to get the GHA Discovery Platinum status during the last offer, it could be worthwhile to have a look at this sale and the rates that are currently offered by the properties. You may be able to save a bit.
