This is pretty simple for me.
Stay once: 2,000 points
Five nights: 10,000 points
Use IHG card: 1,500 points
All of the above: 26,500 points
Stay in May: 2,000 points
Brand bonus (IC, Indigo, Even): 1,500 points
Basically 40,000 points for five paid nights. I had two already planned so need to find three elsewhere. Fortunately low end HIXs count and I legitimately qualify for the state government rate in CA.
