If you want to wear chains/ chain belts to HHN without issue you need to go through security before 5 pm. I also recommend putting the chains in your bag so that you don’t slow down the security metal detector lines.
@DisneyAddict If you get through security before 5 pm they don’t have a problem. I usually keep mine in my purse through security and put it on while on the moving sidewalk to city walk so that going through security is quicker. I wear metal chain belts all the time!
