Heading to Boston with the wife for a couple days before I attend a conference. I'll be moving to the Sheraton near the Hynes after she flies out. We're considering the Liberty and Ritz but are open to others if there are better choices. Which would you all recommend? It will be our first time spending any considerable time in the city. We may have a car, or will take Uber and have no interest in public transit. Our main consideration for hotel selection are room size, upgrade potential (I'm titanium), location for sightseeing, view, and hotel hard product. Breakfast isn't a factor. Thanks!
