Not new, but maybe tell your loved ones, and others who you trust, or are in your friend zone, that you are going overseas, and give them a code only these people will know.
The worst case is that they get emails, how I don't know, that you have been robbed and that you need $.
Maybe use an easy one like that you are the King of Taswegia in your emails.
Stupid or dumb from me, yes, but here is my tale of woe.
A family friend, of my parents supposedly sent me an email, saying that they were robbed in Europe, and I stupidly replied to that email from the family friend, the name was right, everything looked legit.
BUT, after I replied that I didn't have a lot of money, guess what happened, yep, I lost access to that email address.
I had to plea with Yahoo, and in the end, did get my email address access back.
You can also tell your friends/relatives, not to reply at at all to emails that "seem" to be from you.
Have some Euros in your shoes or sewn into your underwear, or sewon into a spot maybe under your armpit.
Take a look at Youtube, and learn as much as you can from there.
Someone I know, who went to France a few years ago, felt a hand went into their trousers pocket!
Personally, though, Europe scares me, and the only place I now ever go, is "tame" NZ! But truthfully, I know that they do have their Mongrel mobs and gangs etc.
Maybe buy one of those Chairman Mao shirts, like the US special forces shirts with large pockets, so you can secure your passport in it, and keep those 4 pockets buttoned down at all times. I have one of these shirts in black!
Worst thing is loosing money, but even worst is loosing your passport!
Enjoy the trip!
