We started our honeymoon in Perth and Margaret River a couple years ago. Pan Pacific Perth was somewhat underwhelming, but alternatives didn't look great either when I was planning... Cape Lodge was fantastic, but so is Margaret River in general if you like big red wines. Had a forest spa suite (Virtuoso agent able to confirm out upgrade in advance), and it was beautiful, comfortable, and very private. Can't recommend enough if any availability opens up for you. Enjoy!
