Have been on the Independence of the Seas (170,000 tonnes?) during a force 11 gale and it never rolled at all. However, it did pitch a surprising amount which made walking down stairs interesting as your weight fluctuated by about 40% over 20 seconds.
Got hit by a 90ft wave at one point which damaged one of the stabilisers (it was folded in and showing offline when I had a look at the control panel in the engine control room), which meant it wasn't quite as stable afterwards.
Also been on the Queen Victoria briefly during heavy winds, the ship took on a noticeably lean, possibly 5 degrees, but was utterly stable in that position.
Edit: just watched that video, the ship is only about 10% of the size of the bigger cruise ships and doesn't look to be making headway, hence the lack of stability.
