When talking about going on a cruise awhile back, someone suggested we bring a magnet to defeat the balcony door sensor that disables the room A/C. That way we can have the door open for the sounds and smells of the sea, but in air conditioned comfort.
Never asked: What size magnet? Will just about any size fridge magnet work?
First time cruiser, Carnival Spirit with friends for their 15th Anniversary and my 38th Birthday, plus Valentine's Day. Very excited!!!!!
