We leave on Saturday morning. Since we're landing at about 10 am and using ME, there's a chance we won't be able to check into our rooms before we head to the parks, much less have our checked luggage, so I need to have what we want for the parks in our carry-on bags. Are gel shoe inserts allowed in carry-on baggage or do they have to be checked? I don't mind taking them out of my shoes for the airport, but would like to have them for when we go to the parks. I thought I'd read that gel products aren't allowed in carry-on luggage but didn't know if that included the shoe inserts. I'd hate to have to throw them out at the airport because they're not allowed, but I want my feet to be happy on our first day. Dr. Scholl is my friend!
