That doesn't explain why (when logged in as Gold) I see this at the Hilton San Diego Gaslamp when I look for individual nights....

May 2 - 3: 45,000
May 3 - 4: 45,000
May 4 - 5: 57,000
May 5 - 6: 57,000
May 6 - 7: 60,000

....and then, when I try to book that as a 5 night award I get quoted 240,000 points.

Based on what Hilton has been saying on here it should be 204,000.

The 240,000 comes from the fact that May 6 -7 has been reduced to zero points and all the other 4 nights have been bumped up to 60,000.

4 x 60,000 = 240,000.

That calculation agrees exactly with the new wording in the T&Cs but not what we've been told on here.
