I've returned from my almost 3 week trip through central Europe (Bruge, Krakow, Prague, Vienna, Budapest).
I brought a neck wallet just in case and never got it out. The crowds were a mix of locals and tourists. Locals don't use money belts or neck wallets. While there might have been nefarious people around I never noticed anyone being bothered.
The Bluffworks travel pants worked wonderfully. The layout is a regular front pocket, a pretty well hidden zipper to an inner pocket and then an additional third inner pocket beyond the zippered one for deep storage. It is accessible with a little effort through a horizontal slit opening at the top of the inner zipper pocket. It is also accessible from inside the pants before you put them on and has a flap closure with velcro. I used this deep inner pocket for passport, debit card and spare cash, none of which I needed during the day but could always get if necessary. I used the left zipper pocket or in some cases the outer pocket for my phone (left handed). The right pocket has a regular pocket which also has a pouch or sleeve big enough for a phone but I kept a money clip with daily cash and a credit card in it. I could have put that in the right inner zip pocket but never felt the need.
I thought they were very convenient and very secure. In addition they look good, are comfortable and dried quickly over night if washed in a sink. Disclaimer: I have no connection to the Bluffworks company, just a satisfied customer.
