Uncovering Hidden Meanings with a Local Guide

I'll be researching, filming new TV shows, and enjoying our Best of Europe in 21 Days tour in the next two months. Each day of my research time I'll be paling around with a local guide. This is my luxury as every minute spent with an expert and translator and friend at my side is filled with learning and insights I wouldn't enjoy otherwise. Anyone can hire local guides to brighten their travels. In Portugal it costs about €100 ($130) to have your own private guide for four hours. Here, my guide Alex is taking me on a little scavenger hunt through Lisbon's castle town (built back when nobles needed a safe place within the castle walls). She's showing me new things I never noticed even after 20 years of visits to Lisbon.
