We will be traveling in January. The first time for us with the Magic Bands. Both my 7 year old and my 4 year old have sensitivity issues, and can't handle watches, bracelets, etc. At Waterparks, I generally put the "bracelet" around their bathing suit strap, or I wear it, an just explain myself. Will this be ok in the parks? Can I wear their Magic Bands? My 7 year old MIGHT be able to handle it, but I know my 4 year old never could... Thank you for any help.
