hotel benefits are not bad. SPG gold can be linked to Marriot gold which gives lounge access and guranteed late check out... the accor benefit platinum i miss a lot. i never triee Hilton/conrad but gold does get good upgrades. also the FHR program is very beneficial. with Jade shangrila i had good welcome benefits.

based on your calculation this is worth 1800 hkd alone to me... but if one never stay in these upscale hotel or travel, obviously platinum aint worth it even for asiamiles.
