Sheraton also has a lounge, so that equalizes vs. the LM. I was there a few months ago, it seemed to have decent offerings in the AM and snacks later.
Hard product-wise, it is almost LC-worthy now...don't think of it as a Sheraton
But I'd personally still do the PT over the Sheraton...I like the location a bit better, and it still is a proper LC after all. And IMO the breakfast is better.
Doing the Westbury in Oct for the first time, I'm sure there will be a report in before then!
