Thanks everyone for great advice. Unfortunately school holidays combined with award space on EK don't give too much flexibility.
I thought about the W since it was close to Atlantis even though I'm much more GH than W.
The rate at the W is $312 and I get breakfast plus a one-time $100 credit or 120,000 points for 2 nights.
The rate at the GH is $231 and I get breakfast plus a one-time $100 credit or 100,000 points for 2 nights.
These are my travel agency Stars rates. I'll also put in for a suite upgrade even though I'm Lifetime Titanium.
