I used the Vera Bradley Mini-Hipster when I was in Universal this past April and just last week when I was at Cedar Point and Holiday World. I would put it under my t-shirt across my shoulders when I went on rides and never had a problem. I put my smaller camera, lipstick, money, small suntan lotion and id.
Good to know. When I carried my VB mini hipster they made me put it in the lockers, but I wore it as a crossbody bag, on top of my clothes. Didn't think about putting it under my tshirt. Also to the person who asked about using a wristlet. Twice I've seen ladies carrying them be told they were considered a loose item and had to be placed either in their pockets or in the lockers. Both times was on FJ.
