I don't find them too bad - as stated, the international properties are way better.

Honestly, CY varies huge from property to property. The key is to get a recently renovated property. The only way to know is to check here / tripadvisor and see...

I'm SPG plat too, and let me tell you that CYs are WAY BETTER than Sheraton Four Points.

Also, "devalue" is the wrong word here. You can devalue a currency (like the dollar... or... a MR point), but if you think they have gone downhill, well then they have just gone downhill...
