Electric bands? I had to come back to this. Being a little gullible, people sometimes like to kid with me. I'm trying to imagine this and failing. Hmmm. Maybe I'll just take what I bought and pray hard - or go to the reception desk if I run out. I tend to be rather sensitive to drugs so am not certain that I want to try a patch and sleep through the cruise. Think good weather for us the first week in September!
