For some tours such as white house, and capitol, we are not allowed to bring items like bags, or food, etc. Traveling with children, this is very challenging, plus we have to bring food all day for one of our kids due to allergies as he can't eat out at all. And we have another child who still requires a booster seat so we were planning on bringing (the bubble bum inflatable one) one in a backpack in case we have to Uber. Where do we put our stuff for these tours? I know there aren't a lot of locker locations.
We will not have a car so it isn't an option to drive in and park and leave our stuff in the car while we tour.
