Here's another of my top peeves:

- All lamps (all 3 of them :-) ) have 40 watt bulbs. Can't read, can barely see to pack on my last day unless I open the curtain.

- on a similar note, finding one or more lamps with burned out bulbs or no bulbs at all. Once checked into an Adam's Mark hotel and when I closed the curtains and went to turn on the lights, discovered every bulb in the room was missing!
