Love the overview hop on hop off gives. Wide variation on the styles and abilities of guides- this can be good and bad. One guide who professed to be an history buff gave great stories but thought he was a stand up comedian- too much! He would say, “up here…” or “where I’m pointing…” (of course with a crowed trolley his arm was unseeable). Other guides simply instructed using “on the left (or right)” and we could find what he or she was talking about easily. So, the ingot was good, the guide was not…
