Our family is taking a trip to rome as my sister is spending a semester in Rome. This will be my spring break and I'm hoping it to be a relaxing vacation. I have been thinking about taking one or two diapers with me in case i find the thought of wearing one for a day. My only worry is if someone stops me to search through my bag and my parents are around as they do it. Is there anything I can do to assure that no one will no the contents of my bag other than the air port members and to have a private search of my bag?
