Karen's hotel story reminded me of something that happened to me about a dozen years ago. I was at a meeting with a group of about 40 other people, staying at a very expensive hotel in Philadelphia, right on the river. My room was at about the 8th floor, but our association president was "lucky" to get a room on one of the highest floors. Anyway, as we checked in, we were all given a sheet of paper explaining that they were going to do maintenance for a couple of hours of their electrical system, so it would be turned off at 11:00 pm and back on at 1:00 am or earlier. Not a problem since we figured we would all be in bed by then since we were having a very long day.
So, after dinner, we got back and went up to our rooms. I got undressed and hit the shower so I could crawl into bed early. Unfortunately, they decided to shut the power off early, at just after 9:00 pm, so in the middle of my shower, it became pitch black! I managed to rinse off and turn the shower off. Luckily, I had left my drapes open so the lights of the city helped me find things and get into bed. However, our president, had chatted in the lobby with a couple of others and found the lights out. There was emergency power in the stairwells and hallways, so she ended up climbing up something like 25 flights of stairs to get to her room on the executive level!! The next day, they apologized and said they would be turning the lights off again, but this time at midnight. I went out and bought two flashlights and a candle in a jar that would not tip over. I also got matches from the hotel.
I also was at the Disney Contemporary Hotel in about 1990 and the power went out not only in the hotel, but at the entire Magic Kingdom. My mother, niece and nephew, and a young second cousin were in the room when I went out for groceries. I came back and had to carry stuff up four flights of stairs, but at least they had good emergency power.
I used to do a lot of traveling for work, but after my two experiences, I never went anywhere without a couple of small flashlights and candles in my suitcase! It also does not hurt to keep a very small flashlight in your purse and a couple in your car.
