336 feet seems high, but I'll go with it since that's what the architect said.
BUT, this isn't a 336 foot building in this image. The Chase Bank Tower a few blocks away is 325 feet tall, and the new hotel appears shorter in this image than that building.
Bank of America Center is supposedly 329 feet, although I found one height that suggests it's 336 feet tall. And I know 301 Congress is 306 feet tall. I had guessed the height would be 290 to 310 feet tall for the new hotel. It's great hearing it'll be 336 feet. It'll be our tallest "all hotel" hotel by well over 100 feet.
