So this is our first time to US/IOA and I like my park bag (alot of snacks, water, handsanitizer, whatever). Figured I would just use the lockers by the ride. Then read about lines to wait in to use a computer to get access to a locker?? We will be there first week of this August. How much of a hassle is it to use the lockers? May have to switch over the fanny/waist pack??? Thanks for any advice.
