During a family cruise on the Celebrity Solstice in November of 2011, I was physically assaulted by one of the crew members. When entering the main cafe I politely refused hand sanitizer and proceeded to enter as I had the entire trip. The crew member lept out in front of me, pushing me into a wall. This upset me to the point that I was unable to be with my family during the arrival to Venice. This was to be the highlight of our trip and was ruined by the crew member's highly unprofessional behavior. I have no desire to cruise on the Solstice again after such an experience.
