LOL.. When don't they leak. I am a frequent bedwetter and when my "accidents" occur-I am a "heavy" wetter. People wet their beds for a variety of reasons. Some have either small bladders or inadequate control. This is NOT the case with me. I can go to a bar and drink all night without using the bathroom. Like a camel! My condition is sleep related. The docs tell me that I am missing enough of some hormone that sends my brain a message to wake up when my bladder is full. Accordingly I sleep like a baby, but pee like a fullback! Although I generally do not sleep with a diaper (heck when you have peed your bed every night until you are 12 and about 1/2 the time since...what is that? about 7,000 wet beds !- you get kind of used to it) when I travel I generally wear one to avoid the embarrassment of peeing a hotel bed during an extended stay. But heck, most of the time they leak anyway. So instead of getting a lake you get a 3 foot wet spot. I do find that the hotel staff are relatively discreet once they figure out (from the soaked disposable in the garbage can) that you at least tried.
