Remember waist money belt, or neck pouches, or leg safes, are mean to say UNDER your clothing all day. You don't get in and out of them. This is very important or basically defeats the purposes of having something hidden, if you fish it back out in public!

Keep a small daily amount of cash in a pocket or purse you can easily get at.

Sure, I would get them for the kids too. Partly because it would be good practice for them, but also it gives you 3 more places you have money stashed, should anything happen to one person's.
