Holy smokes! When I started commenting, there wasn’t a whole lot of activity here, but now!
Doc, I think you’ve got a whole lot of advice, enough so’s you can pick and choose. But I’ll add in a bit more.
If you ever travel out of the USA, or intend to make it a regular affair, then you need to get into the habit of carrying cash. $200 is a good start (carry around USD200 in equivalent local currencies is usually overkill). Reason is, not every street vendor and/or eating establishment overseas will accept cards (for that matter most smaller shops won’t, either). And some places, ATMs are few and far in between.
Belts are meant to be used to hang stuff off. For men, anyway. If you really need a flashlight, where better?
And yes, Mums get treated as walking repositories and storage spaces. 
This is quite standard, I believe, and mostly unavoidable.
