Great news, but it doesn't really benefit me. My corporate rates with SPG have included HSIA now for about 2 years, so I won't see any difference. Regardless, this is a good step for Platinum Members across the board.
If I could toss out one little thing, it would be this: I would LOVE to have seen the announcement be a "YOUR CHOICE" thing for Platinums: either comp HSIA or breakfast in the restaurant. My preference would be 100% for breakfast every time, every month, every year.
Just my $00.02. Not complaining, folks. Just sayin'.
