This is going to be the dumbest question I have asked thusfar, but when I was in Calgary recently, my two friends and I had our respective hair-doing products plugged in and we also had a radio and a video camera (to charge the batter) plugged in at our hotel and we ended up kind of short circuting our room and a few on the same floor (oops!)...Do we need to worry about doing this again on the cruise if we use a powerstrip? It was rather embarrasing
