I suspect the Queen Elizabeth is more stable than other ships. The two places the sea was rough were in areas than many on the Alaska board say are rough and it wasn't during the inside passage itself. The captain was also able to get us extremely close to the Hubbard glacier. The naturalist on board was quite surprised at how close she got. We've only ever done a Caribbean cruise on the Allure, so I don't have a lot of experience, but we did prefer the Queen Elizabeth because it suited us
