Yep. Now that you can get the likes of the Dorchester for not that much more than the Park Tower, once I qualify for Platinum, I'll be defecting to the Dorchester where I had a very nice stay the other day.

I would stay loyal to Starwood for Heathrow hotels (there aren't much else there anyway) and also in various European and Australian cities, but London selection is just not good enough compared to the rest of the places.
