I'm Silver and stayed at Hilton Adelaide for the 2nd Test but with a QF booking so I could use a hotel voucher. SFA benefits as a Silver so got what I booked and only missed out on some points.
It's a pretty tired hotel and needs a reno. Bedding is really, really comfy. Room was clean and had a SHUB and severe shortage of available power outlets. Nothing accessible near the bed so had to unplug a valuable light to be able to plug in two things.
Terrific location but on Sunday mornings it's a ghost town. The markets were closed which is mystifying.
