I once stayed at the Westin in Guam during a Pacific Typhoon where the majority of the island lost power and we didn't complain because it was a Typhoon. The Westin did take good care of its' guests during and after the storm to a point of where I didn't feel aggrieved by the situation.

Fast forward a few years later where a hotel in New York lost power for half of the day due to construction work in the lobby, I felt aggrieved because that was a controllable issue and the hotel staff couldn't have given two koppecks about the situation so a complaint was filed with Marriott on this one versus the act of god one,
