St Augustine is a town rich in history so having a tour guide to explain and show you the sites is always a good thing. However, most of the history is so close together that I, personally, think a walking tour might be the way to go, if you're able to do so. The trolley literally stopped around every corner and it felt like we went in circles, which, we probably did, as everything is close. Our driver also felt the need to yell out her name after she'd ring her bell at EVERY stop, which got to be quite annoying. Maybe it was just me. She was a nice person.
