InterContinental just tweeted about their Las Vegas award flash sale. You can get both Venetian and Palazzo at 50% discount of the usual number of Priority Club points required. The number of points required during this sale is 25K PC per night.
The link that was on the twee didn’t originally work, but after sometime the special page for this promotion was up as well.
The discounted point rates do show up on the search as well.
Personally, I wouldn’t use 25K Priority Club points for a hotel costing $150 considering all the points that I would earn from that rate as well. (See here how many points I have earned on average on my paid PC stays this year. ) This offer might work better, if you choose more expensive weekend nights.
