Things could have been worse. I was staying with my wife at the downtown Chattanooga Marriott on the top floor a few years ago when a big storm came through in the middle of the night. Lightening hit the building and set off the alarms. We had to walk down the stairs as quickly as we could and then go out into the rain to wait until the fire dept. got there. We then had to wait 30 minutes to get an elevator back to our floor. Then guess what? An hour or so later, the alarms again went off and we had to go through the whole exercise a second time.
I definitely wasn't happy, but guess what? There just wasn't much the hotel could have done differently. And just because I was inconvenienced, doesn't mean the hotel has give me something extra. Especially given there wasn't much they could have done differently.
Now if the hotel had decided to "work" on their alarm system in the middle of the night and directly caused the problem, I would have a different opinion. But as long as the hotel was reasonably doing what they should be doing, then "stuff happens" and you go on.
